Further, this thing defaults to 720p! There is no way (as of yet) to get the board to run at 1080p. I've modified the hell out of the xorg.conf and it fails because the /dev/fb0 is set somewhere in the (difficult to modify) boot configuration to be 1280x720!
:sigh:
Back to hammering away at the Raspberry Pi I guess... at least until the lima driver (http://limadriver.org/) guys bend over backwards to reverse engineer ARM's stupid, proprietary silicon...
