Linux newbie needs help.

I have a 2003 vintage Gateway with the notorious 82545G integrated graphics. (Lucid hangs regularly.)

For the last week I have been trying to get the Bitdefender Rescue CD (based on Knoppix) to give me a GUI with no luck. I tried as many of the cheatcodes as I thought might help. (By the way, are the cheatcodes intended to replace or append to the other boot parameters?) What I get is a flash of the screen followed by a blank screen. Ctrl Alt Backspace and Alt F3 lands me at a bash prompt. I can mc to xorg.conf, which I have edited, saved, and tried to restart xserver with no luck. I have tried copying portions of xorg.conf from ubuntu 7.10 - that didn't work. The command dpkg-reconfigure doesn't work. Restarting xserver fails.

Results of lspci -v are as follows:

After massive frustration and confusion, I'm tapping out. Can somebody throw me a bone here? I don't need the GUI to be pretty, just functional at, let's say, 1024x768. How do I get this GUI to run? Luchadores, ayúdeme por favor!

Thanks for any help someone can offer.
