Lost video signal when screen resolution changes

[agntsgotnosecret]

Here is a list of my hardware and install method:

 

Motherboard: GA-EP45-UD3R

Processor: Q6600 @ 3.3 GHz

Video Card: EVGA nVidia GeForce 9500 GT

Cooling: Arctic Freezer Pro 7

DVD-ROM: LG 20x Sata DVD Burner

Hard Drive: WD 320 GB SATA II 16 MB Cache

 

grub-dfe --> Retail Mac OS X Leopard (10.5.6 + software updates)

 

I recently purchased a 24" LCD that has a native resolution of 1920x1080. Prior to this, I had a 21" LCD which I'm assuming had a different native resolution. Anyway, my dilemma lies with games and video resolution. In particular, Warcraft III. I had Warcraft III installed and running perfectly with the 21" + Leopard combo, but when I reinstalled Leopard with the 24" monitor, the game launches and I get sound, but the video is completely black. A signal is present, and I hear the game's audio, but the screen is completely black. Pressing Command+M does not minimize the application, and I essentially am unable to return to the desktop and I have to forcefully reboot. I didn't want to investigate the dual-boot Vista/Leopard route as installing an entire operating system for one game seems a bit silly. I've tried changing the native resolution in OS X to no avail.

 

Any ideas?

 

EDIT:

 

The problem appears to be related to the video kext.
