Additional changes necessary to make this work:
In geode_driver.c:
Line 1414: minPitch = 320;
Line 1445: PitchInc, 240, 1024,
Otherwise, you'll be able to display the resolution, but it will always be
in virtual screen with a minimum area of 640x480.
However, with the change put in, you end up dealing with the notorious Geode
XF86Config Virtual entry wierdness, where the Virtual entry needs to be set
to an odd setting like "Virtual 513 384" or you get display problems.
Because of the Virtual stangeness, I'm not sure whether these changes should
be added to the driver in CVS, but this may be of use to others, especially
since the Geode is often used in embedded PC's that need to display on small
screens with lower resolutions.
