I'm having the same problem for TSL as manoface, same graphic card too. Well actually I think mine is an 8600m GT.

EDIT: Ok I did some snooping around the swkotor2.ini and found something. I opened it and found that there was a blank area at the very top, just above [display options]. I removed the blank area, saved the file, and attempted to run TSL. It ran the game.

EDIT: EDIT: Well it seems to be a more random occurrence if the game works or not. Sometimes I get it to work other times it doesn't. I think there is still a bigger answer here.
