This is the crash screen:
Attachment 742

I have the G31M-ES2l and the graphic card Asus GeForce 7300GT 256mb.
Output through DVI.
Snow leopard with kexts as in sk1nhd33ts guide.
Chameleon RC 2/3 boot0 boot1h and netkas 10.3 boot. No efi string - GraphicsEnabler in boot.plist. Kext Utility.

I don't know much about Quartz extreme and Core Image except that they are supposed to make the GPU do more of the work.
The 7300 is pretty weak though so I don't know what the difference would be.
The Wikipedia entry for Core Image list the 7300 as one of the cards used by apple for core image and notes that "any GPU capable of handling Core Image instructions is also Quartz Extreme capable". I used a trial version of iMaginator and ran this test I found. There was no difference under 32 or 64 bit (around 2 min 40 sec). I also used Core Image Fun from the developer tools. Transitions and effects worked fine in both 32 and 64 bit. (it crashes when using large pics like the example pics). Quarts composer also seems to work.

Xbench gives me slighter higher value for quartz and openGL in 64 bit…

Clicking the "Open in 32bit mode" under 64 bit kernel doesn't help Chess.
I also tried out an app called OpenGL Extensions Viewer. No difference in cpu % while testing.
