2 - Also I added some user's tests I saw in the forums that allow these cards to get the DVI or VGA working.
3 - Get and change the screen resolution as discussed above. Although you can comment here, but this topic is not intended for this.
The most important part of this topic, anyone with one of these cards can test the results we would serve users with different cards, in short if a user gets QE / CI in one of these cards will serve for all. Why? because they are using the same core
Mobility Radeon HD 3100 - RV620
Mobility Radeon HD 3200 - RV620
Mobility Radeon HD 3410 - RV620
Mobility Radeon HD 3430 - RV620
Mobility Radeon HD 3450 - RV620
Mobility Radeon HD 3470 - RV620
Mobility Radeon HD 4200 - RV620
Mobility Radeon HD 4225 - RV620
Mobility Radeon HD 4250 - RV620
Mobility Radeon HD 4270 - RV620
Radeon HD 4200 Graphics (785G Chipset) - RV620
Radeon HD 4250 Graphics (880G Chipset) - RV620
Radeon HD 4290 Graphics (890GX Chipset) - RV620
FirePro 3D V3700 - RV620
FireMV 2260 - RV620
Other cards that I'm not sure if it would work:
Radeon HD 3450 - RV620 LE
Radeon HD 3470 - RV620 PRO
Ok, you have one of these cards and you know how to change the screen resolution so continue...
- How to obtain ATI card acceleration on OSX ?
Support of ATI cards is made by 2 kexts :
- A framebuffer, located in /System/Library/Extensions/ATINDRV.kext/Contents/PlugIns/ATY_Somefile.kext
This one is responsible of 2D support, including resolution change, output signal handle, and refresh rate.
- An acceleration driver located in /System/Library/Extensions/ATIRadeonXXXX.kext
This one brings hardware acceleration allowing use of QE (Quartz Exterme) and usually CI (Core Image) too, except on some older models
which only support QE.

* The same but with some extra information: http://osx86.fujiliv...ard-information
* Here you can check and compare ATI cards, but the important is to determine which framebuffer need the core:
RV620 use ATIRadeonX2000.kext so it's the reason because you can change the screen resolution using dong's kext.
Here a collection and tests about How to obtain QE / CI: http://www.insanelym...uffer-solution/
In this topic some users explain how the ATI Mobility 4xxx works with QE/CI: http://www.insanelym...ci-testing-107/
In the comment #9 of this topic: http://www.insanelym...0-on-os-x-1063/
you can see a user with an ATI Mobility Radeon HD 3400 that says :
I have installed the RadeonHD kext, and resolution is much higher. But it seems I still do not have QE/CI enabled. How do I turn the feature on ?
After a few tweaks, it seems QE/CI is enabled but I still see no difference.

tileWidth = 256;
wmarsh says in this topic that is possible to obtain QE / CI on Mobility 34xx cards:
Attached files in this topic: http://www.insanelym...or-dell-studio/
How to quick patch Framebuffer's explained for obtain full QE CI working:
For Radeon HD 3XXX and prior choose Sharks,
For Radeon HD 4XXX choose Birds,
For Radeon HD 5XXX choose Monkeys.
Some other important info and comments I collected:
"Maybe with the edit of the framebuffer you could have QE/CI....but you have to set the right values, i found some framebuffers that you could edit but i don't know what are the offset in ATIFramebuffer executable....i attach you the official framebuffers to edit for QE/CI for ATI Mobility 3xxx, you have to follow mucha's guide but at the end you have to edit one of this framebuffers and you should have QE/CI
for dmesg you have to install RadeonHD by dong,restart and then in terminal type dmesg > file.txt and you will have the values of you're mobility!!"
"You have to follow mucha's guide and at the end download Sharks_FB.rtf(for mobility 3xxx) and Monkeys_FB.rtf(for mobility 5xxx) you need of this file because in it are the name of the framebuffer for your mobility(s) and you need xcode to find the offset of the framebuffer that you want to edit!"
And look at the other Leopard1993 comments on the second page of the post: http://www.insanelym...io/page__st__20
"mucha's guide says that you have to connect another monitor HDMI/VGA/DVI to your laptop and than do dmesg in terminal"
"If you have windows you can dump your bios with everest if you haven't windows use bcc9's tool"
Another info: http://forum.voodoop...pic,1959.0.html
I'm not sure about if this user get the acceleration.. her last comment in this post is confusing: http://www.insanelym...radeon-hd-3430/
ATI Moblity Radeon HD 3650 saying that QE/CI is ENABLED:http://www.insanelym...3/page__st__340
If other users has obtained QE CI with 4xxx cards (that aren't on my list), we can obtain it.
So.. We are a lot of users, we can do lot of tests
Some time ago was said that ATI Mobility Cards aren't supported on OSX.. day by day you can see new ATI Mobility cards running with QE / CI..
Update 29/11/2012, Another CLEAR guide to get QE / CI in Snow Leopard:
I don't understand why AIDA64 (ex-Everest) show this: (look at the device name ¡¿?)
Video Adapter ATI Mobility Radeon HD 3430
Device Name RV610/RV620
I don't understand why aida64 is reporting that reference to the RV610 core, but this increases the probabilities of obtaining acceleration .. Also considering this:
ATI Radeon HD 2400 XT & Mobility HD 2400 XT are based on RV610 and have QE CI in Leopard version see here: http://www.insanelym...-2400xt-0x94c1/
*old news (maybe useul) about 2400XT in Leopard:
And in Snow Leopard too:
..other useful info: http://osx86.fujilives.com/
..other information that I have discovered today is that you can use ATIRadeonX2000.kext from SL in Lion.. but this is another issue
I need testers and feedback, the idea is to post here the tests to find what works and what doesn't!
don't forget: persistence leads to success
