So none of the v3.7 series will work with this GPU/panel. 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 http://www.reactivated.net/weblog/archives/2006/01/using-git-bisect-to-find-buggy-kernel-patches/ 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)?
