Okay then, that possibly makes sense...
Just to double check, could you run the
finger_trace tool, and see if it actually draws stuff in the right place (say, a short swipe in the top left corner).
Keep in mind that it'll fight to the death with whatever's attempting to redraw stuff below it ;p. (Hit Ctrl+C to quit).
Ideally, it would be amazing if someone could test this in all four rotations:
./fbdepth -R UR
./fbdepth -R CW
./fbdepth -R UD
./fbdepth -R CCW
But admittedly, just UR would be a good start

.
I also wouldn't mind having a look at the full terminal output of these runs

On another matter completely, if someone could poke in
/sys/class/backlight to see where the frontlight & LED controls are hidden, that would be neat (It *looks* like it's the exact same thing as on the Libra, but I don't recall if anyone actually confirmed that ^^).
