Ignore the unhelpful jackass above.

Here's one resource:

http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_Correct_the_Graphics_Resolution_.28Intel.29

and here's the package containing the drivers:

http://packages.ubuntu.com/feisty/x11/xserver-xorg-video-intel

I had the same issue. What I had to do is install the package above and manually tweak my xorg.conf file much like you have been doing. I got it to work after a bit of futzing. I'm not a programmer, but my suspicion is that the system needs the driver package to be able to display 1280x800.

Good Luck!
