I could help you guys...
The bootloader we are working on has GMA GraphicsEnabler auto-injection...
If the GMA X3100 card isn't present in AppleIntelGMAX3100.kext and AppleIntelGMAX3100FB.kext (thus not 0x2A028086 / GMA 965) you need to patch the binaries in both kexts with a hex editor (search 8680022A and replace to your card id byte swapped, thus if your card = e.g. 0x2A04 it becomes 8680042A, search and replace all) and modify the IOPCIPrimaryMatch key in the 2 plists.
In /Extra/com.apple.Boot.plist add:
Replace /boot with the one from the GMA945 fix chameleon package.
Install 2 modded kexts under /S/L/E and reboot...
It should work now after reboot, both resolution and CI/QE/OpenGL...
