NSCXP2005 is right. I've found this out just before opening the thread again for replying that i've found the solution.I was just a little bit to careful about my chameleon installation.
To sum up:
1.Boot your Ubuntu(or whatever) Linux Installation and go through it until you hit the Partition Selection screen.
2.Make sure your / filesystem is ext4(since others have reported that ext3 is somehow NOT working)
3.Make sure you select your / PARTITION(yes partition) for bootloader installation this will install the grub-stage1 loader into the GPT Partitions Bootblock and make it therefore detectable by Chameleon.
4.Have fun

Thank you all for your help

i've just took the installation stick and booted up the Mountain Lion Partition with it.I think your problem is dual booting related. are you on a mbr drive? if not try to unconnected all other drives beside the mac os x drive and then try booting up with the installation usb stick(just choose the Mountain Lion Partition when Chameleon appears) and if it boots then try reinstalling chameleon. also make sure you select the correct drive in bios boot orders.

for qe/ci - if its not working oob - check this here:
 QE_CI Exotic patch Mountain Lion GM.zip   1.63MB   10 downloads
just drag both kext files into the kext utility app. i have a radeon 4890.
to get the garbled gui at first i had to boot with GraphicsEnabler=No.

for the audio. make sure you install the kext with the Kext Utility app i've provided. Also make sure you've installed the DSDT.aml i've provided.Furthermore make sure you don't use that one they've inserted into my post. download this one:

http://freakshare.co...A.kext.zip.html
and install it with the Kext Utility App

if you can't follow my instructions just say it.if you want i can make a video for you,but i'm on vacation for a week first.also i could help you with team viewer or vnc if you want to.you write a pm and i'll gladly help you in a week.

hope this crappy english helps you.

Hey guys,

Just wanted to share the outcomes of my work with you. got my rampage 2 extreme fully working !with! Audio.

Instructions:
1.Use the MLionize Script to make your boot medium.
2.Install(maybe you will need GraphicsEnabler=No)
3.don't run the finalize thing
4.start again with the usb stick
5.install chameleon: Chameleon-2.1svn-r2042.pkg.zip
**maybe you don't need this step**
6.make a new folder called Extra on the root of your installation hard drive
*******************************************
7.copy this into it:  DSDT.aml.zip   18.3K   47 downloads
8.generate a smbios.plist place it in /Extra too(or just use the one from the usb stick)
9.generate a com.chameleon.boot.plist place it in /Extra too(or just use the one form the usb stick)
(Chameleon Wizard is a good tool for 8. & 9.)
For Audio
-Download this:  Kext Utility.zip   267.76K   25 downloads
and this: ***wrong one look at the bottom****AD2000b-ML-10.8-AppleHDA.kext  patch credits to ErmaC here post #70****

-Extract both and just drop the AppleHDA.kext at the Kext Utility App
make you you've installed the correct DSDT(the one from 7.)

-reboot and enjoy

everything seems to work now. though i don't tested sleep yet. I'll report back when i've tested it. sleep works well.

edit:// who the {censored} changed the AD2000B kext? THIS IS THE WRONG ONE! this kext is missing the Info.plist at AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.plist! if you don't believe me check it yourself. i've fixed that problem. thats why its working for me -.-
here is the CORRECT File: http://freakshare.co...A.kext.zip.html
CREDITS GO to ErmaC! but i've fixed the kext he provided here: patch credits to ErmaC here post #70

Ok guys i fixed it. Just forgot to update the Kernel Caches after I Installed the Kexts from fantomas. -.- Single Display is working now but no dual display but this is a problem with the Motmot Personality which i can fix myself. Many thanks for your help A Difference from 10.7 is although definitly that the 4890 isn't wokring anymore without the qe/ci patch. althought this isn't a problem if you know it^^

For everyone reading this thread:
GraphicsEnabler=Yes
fantomas 48xx qe/ci Enabler kexts
!!use cvads kext utility to install the kexts!!

and then everything will run smoothly.

see you

sorry my internet was messed up yesterday evening -.- i tried this though but it doesn't seem to work. Also it seems like i don't even get this ***DEVICE IN SLOT-1*** Message which i usually get on lion before the gui starts up. To me it really looks like chameleon isn't injecting the graphic card correctly. I will try to change the pcie port of the card now because i've changed the port recently to the 2nd one, because the first one had some strange problems. Furthermore i will try to set up vnc on mountain lion and try to vnc into it when its booted up fully with graphicsenabler=yes and post some ioreg stuff. Will report back soon.
