A slight update: Manwe's patched AppleIntelSNBGraphicsFB.kext for Lion seems to work flawlessly in Mountain Lion. Only things that are missing now are
- sleep
- battery indicator

as always, any hints are more than welcome

Hey Crumpo, how is your T420 working without the laptop dock? Like as a standalone machine, is the resolution and QE/CL working fine? I never managed to get full QE/CL even with 10.7.2.

The internal display works fine with the patched kext provided in the first post (they are for lion but do the job in ml just as good). QE and CL both work without problems, and the internal display is at its full 1600x900. Display on displayport works fine, too

If anyone can help me I will be endlessly grateful. Here is what I did for Mountain Lion.
I installed using ######. Boot up from USB Drive bootloader into Mountain Lion.
Resolution is messed up but should be fixed after DSDT Patch right?
Run ###### with ONLY UserDSDT (Manwe150' from 1st post) and SMBIOS Macbook Pro 8,1.
Reboot
Kernel Panic
The Kernel panic traces to AppleIntelCPUPowerManagement for some reason. Hmmmmmmmm Anyone know what I can do?
I can easily get back in to edit the files since I have another partition with 10.7.2 installed. I've had 10.8 installed on a different partition.

Great news,

I have working sleep in Mountain Lion!

1. execute from terminal

Quote

sudo perl -pi -e 's|\x75\x30\x89\xd8|\xeb\x30\x89\xd8|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC

2. Install the attached kext

Hi Crumpo, I ran the script and installed the kext, but I get the spinning wheel at the login screen when I return from sleep. Any ideas?

[stevenplanet]

Hey a little help here So I installed 10.7 as per Tonymac's guide with a T420 Intel HD 3000. No nvidia at all. I booted into, installed DSDT and everything worked beautifully. I didnt even patch any kexts yet! Ran ###### and rebooted. downloaded 10.7.4 combo update, the download one not the software update. Ran ###### again and rebooted. now this is what I get. It shows up after the spinning wheel under the apple. I can enter in my password and press enter and the lines seem to change. its booting up fine but the graphics are messed. anyone wanna help me out? Hehehe.

I did! You mean just the AppleIntelSNB kext right? Thats the only one I saw in the first post. I got in with GraphicsEnabler=No and used Kext Utility to rename the original to *.bak and place the modified one instead. I rebooted and its fixed but I get awful system hangs now. As much as opening chrome or safari will freeze my T420 for 10-15 seconds. Quite annoying in fact....but at least its working I guess.

As for the hangs, there are posts further up from folks who have similar issues, maybe there is something that can point you to some kind of solution. I use two external screens via digital out from my docking station and did not have any graphic problem whatsoever in either 10.7 or 10.8.

Thanks, it works now. I had replaced the AppleIntelCPUPowerManagement.kext that comes with 10.8 with the one I had customized in 10.7.2. I think this was causing the issue when waking from sleep. I have put back the kext from 10.8, removed the kernel flags (-allowAppleCPUPM) and it works fine now.

Just one more question about the org.chameleon.Boot.plist.
Can you share your file? I have a very simple one now, that seem to work fine, but I'm not sure if the C-states, etc are needed or not.
Here is my org.chameleon.Boot.plist file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com...yList-1.0.dtd">

<string>mac-es</string>
<key>Theme</key>
<string>bootcamp</string>
<key>Timeout</key>
<string>1</string>
</dict>
</plist>

Any suggestions?

Thanks a lot for your help, this is working great...

Hi stevenplanet, I have similar issues, some hangs... I have not figured out when they occur, but every so often, I get them.
The screen starts to get messed up,  it's like the video memory is getting overwritten with a lost pointer... when this happens, when I open a menu of any application, I get squares from other regions of the screen. The screensaver also has squares of the screen with pieces of the desktop, etc.
This is not consistent though, it only happens sometimes.
Must be related to the AppleIntelSNB or the dsdt that is not fully compatible with our model. I have an i5 (not an i7) and I am using the DSDT posted on the first post.
Maybe this is the issue?

Yes. The fix I found was that if I installed just 10.7, (the original release) instead of 10.7.2,3, or 4, the graphics glitches, artifacting, squares, and ring freezes went away completely. Everything works beautifully with full QE/CL. I have no idea why haha. I basically did a vanilla install using unibe@st and then just followed the instructions in the first post. Everything works except my SD card reader. Good thing im not a frequent photographer. What are your exact specs by the way?

T420 upgraded to Mountain Lion - now a complete success.

Update: changes for 10.8.2 10.8.3

Thank you to joshhh, manwe150, crumpo, verleihnix, bcc9 and a few others on this thread…
My system (i5-2520M/8GB/HD3000-only) is working better than ever on 10.8.0 10.8.2 10.8.3

(/Extra and System/Library/Extention kexts attached - hope it will help someone else)

Working:

• Audio
  
• Video
  
• Network - wireless with ASUS USB-N10 (similar to AirLink101)
  
• Battery
  
• Sleep and Wake
  
• SpeedStep - states from 8x -> 30x – geekbench of 6427 6534 – not bad.

Not working:

• native Intel WiFi
  
• Ricoh SD card

Steps:
Upgraded from 10.7.4 but removed all custom kexts so started with vanilla 10.8.x

Updated by USB - UniBst v1.5 method
added dsdt.aml to USB and then Booted with flags: PCIRootUID=1
used external USB mouse + external HDMI/Display port attached Monitor

Added kexts one at time – see list below:
Note: Using slightly modified "manwe150" dsdt.aml

Notes:
• Still get some LCD graphics buffer hangs – but not as often as 10.7.x (use an external monitor mostly)
• When I upgraded from Lion, I used MultiBst added NullCPUPM initially but then removed afterwards when I started using a bin-patched AppleIntelCPUPM kext
• Sleep:
o in org.chameleon.boot.plist, removed generate P-states and C-states=Yes  or I get KP.
o Removed SleepEnabler and NullCPM and removed generate P-states from Boot.plist
• Battery –  VoodooBattery is working (after rollback to AppleACPIPlatform.kext)

Kexts used:
– FakeSMC.kext = v4.3.x + new sensor pack in Plugins
o ACPISensors.kext
o Uses new HWMonitor.app (kozlek)
– Audio:
o AppleHDA.kext v10.8.x (patched for CX20590)
– Network:
o AppleIntelE1000e.kext (put in IONetworking.kext/Contents/Plugins)– Mouse/Trackpad:
o    VoodooPS2Controller.kext (has VoodooPS2Keyboard + thinkpad+ nub)
– Sleep/CPUPM/Battery
o Patched AppleIntelCPUPowerManagement.kext (10.8 version)
o Rollback to AppleACPIPlatform.kext (v 1.3.5 from 10.6.x)
o VoodooBattery.kext (v1.3.3 for Lion/ML)

– Misc:
o Patched AppleRTC.kext (10.8 version) not sure this is needed but didn’t hurt.
     o    AppleGraphicsPowerManagement.kext (edited info.plist to add vendor info)
     o    IOAHCIBlockStorageInjector.kext (to get DVD and eject working with apps)
     o    AppleIntelSNBGraphicsFB.kext - replaced 4th buffer to use VGA.    

Updated: 11-30-2012:
see post #164 for 10.8.2 kext pack. (has FakeSMC 4.3.2 + HWsensors, and newer AppleHDA based 10.8.2)

Updated: 03-22-2013:
see post #238 for 10.8.3 kext pack ( new FakeSMC and new VoodooPS2Controller + AppleHDA based on 10.8.3)

Just asking but does your laptop work fine without being attached to an external monitor? Last time I updated to ML I had really horrible graphics lags known to the community as ring stalls.

Thanks to this community

my 10.8 pack is here
it's a bit different from tluck cos it doesn't work for me.
my pack and tluck dsdt.aml work but my screen display the same thing 4 times (4 little screens on one)
so i use my pack.
changes concerne :
AppleHDA.kext   must be cos i don't use dsdt.aml
AppleIntelCPUPowerManagement.kext
FakeSMC.kext
AppleRTC.kext
----
better than nothing i have (with it)
- LCD video, usb, keyboard, red point are ok
- bluetooth ko, sound is not working with my pack, sleep and wake ko
i did not test :

- extra video (external vga or hdmi) video is ok
- card reader (no card to test)
- no extra port except usb
(edited after tluck questions)
so my pack is not as good as tluck

I'll test tluck pack again ASAP

[tluck]

@stevenplanet - to answer your question - yes it works "fine" .... BUT yes when doing certain graphic functions as simple as Mission Control, the system does get ring stalls/ buffer hangs.  My work around is posted in an earlier item. When i using the system in pure laptop mode - i.e. using just the LCD display (LVDS only) i often resort to using the Xcode toold Quartz Debug to disable 2D acceleration. at home, i usually have it in a laptop docking station with an external Display-Port attached monitor (and often with  lid closed). So without LCD in play, that seems to eliminate these buffer stalls. Even so, with ML, i seem to see less of these hangs and can often use it just fine for email and browsing w/o quartz setting.... I just stay away from Mission control (or hot corners)!

@tetonne - can you  be more specific about what is not working? my laptop is the same T420 type 4236. you mention you dont use dsdt?  it has graphics, audio, usb fixes so its essential IMO.  i noticed.... you have an older FakeSMC? i dont use sleepenabler or NullCPUPM anymore.
