I think this question was never answered, so I'd like to bring it up again.
I am also intrested in getting 320x240 fullscreen to work in my Intel G965.
Neither 915resolution nor xrandr list that resolution.

Is it at all possible? Alternatively, is there a way to configure
X to simulate 320x240/fullscreen when an application requests it? 
Right now I always get 640x480 with big black borders, which reminds me 
of the "good" old XFree86 3.x days...
