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.
