In the BIOS for my mainboard, there doesn't seem to be any mention of
resolutions. But my video BIOS does support that resolution, at least
according to what shows up in /sys/class/graphics/fb0/modes
and /sys/bus/platform/drivers/uvesafb/uvesafb.0/vbe_modes
And yeah, in the "Caveats and Limitations" section of
linux/Documentation/fb/uvesafb.txt , spock does make it clear that
uvesafb can only use modes supported by the video BIOS. I don't think
I could live with that -- I'd go back to vesafb if it didn't WFM.
