After some debugging, it looks like the low-level drivers (omap dss2,
omapfb) are doing things correctly, but for some reason, X is requesting
480x640 no matter what - even when the autoconfig on the frame buffer
device returns a virtual 640x480. 

Does anyone have pointers to how exactly X goes about setting its screen
resolution when xorg.conf is essentially empty?  Any overrides I've
thought to add to xorg.conf have no effect (modelines, virtual screen
resolutions).  I also tried changing MACHINE_DISPLAY_WIDTH/HEIGHT_PIXELS
in openembedded/conf/machine/omap3evm.conf, with no success.

Thanks,
