Hm, that's still a few hundred relevant commits intermingled with a
few thousand that likely don't matter ;-) Can you please attempt a
kernel bisect with git? For a nice howto check out

Also, can you please check which of the different backlight controls
in /sys/class/backlight work on 3.6 (and whether any of them still
work on 3.7)?

Thanks, Daniel
