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.
