the screen res is located here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\Current\System\CurrentControlSet\SERVICES\ATIRAGE3\DEVICE0

Note that ATIRAGE3 is the video card installed, you woyld have to ENUMKEY if you wanted to script it.

I'm not certain if wintendo keeps their stuff here...
