If applications call something like
 buffer = SDL_SetVideoMode(0, 0, 0, SDL_FULLSCREEN)
(where the '0's can be whatever) then the result is broken. I think that this is because SDL is reading the xrandr stuff and getting confused by the fact that the screen is rotated by default:

For example:

$ xrandr
Screen 0: minimum 256 x 128, current 1280 x 800, maximum 2048 x 2048
LVDS-1 connected 1280x800+0+0 right (normal left inverted right x axis y axis) 0mm x 0mm
   800x1280        0.0*+
HDMI-1 disconnected (normal left inverted right x axis y axis)

The mode reported is the modeline from the tegra driver, but it's
rotated (from the Xorg.0.log file):

SDL isn't spotting the rotation and doesn't understand to mutate the
modeline accordingly. This may well be an upstream bug.

I'm currently poking through the SDL source to see where it's getting it
wrong...
