[Problem]
X is trying to boot with 1400x1050 when it should be booting 1280x1024,
resulting in a black screen.  If a lower resolution such as 1024x768 is set via
xrandr in ~/.xprofile, X comes up okay at that resolution.

[Discussion]
User had been running with -vesa on Hardy, but on installing Intrepid, found
that it was failing why trying to use -ati.  Manually specifying to use vesa
worked, but the question is why did -ati not work?

After some debugging work, it was found that -ati would come up fine on 800x600
and 1024x768 if specified in ~/.xprofile.  Specifying 1280x1024 with xrandr did
*not* work, even though both the monitor and video card support that
resolution.
