hackintosh - Intel graphic card resolution
http://www.insanelymac.com/forum/lofiversion/index.php/t5513.html
For G33,Q33 Intel chip, there's no ktext for it; however you can do this to alter the resolution:
vi /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
Edit string value for Kernel Flags,
Kernel Flags
"Graphics Mode"="1280×1024×32"
After reboot, it's default to 1280x1024 instead of 1024x768, much better.
This works on iDeneb 10.5.6.
