i915.invert_brightness=1

[Grethus Bode]

Hello dri developer,

I have a laptop (Acer Aspire 5336) which needs the i915.invert_brightness=1 option set to get the brightness correct.

running Linux 3.7.10-1.16-desktop, openSUSE 12.3 (Dartmouth) (i586)

Via modinfo i915 I found this mail address and a note to send some info if my machine needed this option.

Via hwinfo --gfxcard I got this info, I hope it is enough:
