Jimmy sent me some more info, sounds more promising.

FYI, here is another graphic card that supports 16:9 800x480. It’s AOPEN PA315 Pro-TVH. You can visit the follow URL for more info:

I believe some older Matrox video cards support 800x480. I don’t know about now. And I think
http://www.omegacorner.com/ offers drivers for Nvidia, ATI Radeon, 3dfx that enable 800x480. But this has not been confirmed. Hope this helps.

I think I may look at the drivers he mentioned and see if they work. When I hacked my nVidia drivers myself the picture was all screwy, but maybe these work better for some reason.
