Linux 2.6.39-rc5

> Go forth and test,

Doesn't work on my notebook with i915/KMS. But then again, neither did
2.6.38 or any of its stable releases. The last working version was
2.6.38-rc8. The problem has been reported[1], but the bug got closed
in the wrong assumption that the bug is fixed. I reported that, too.
No reactions to that.

The bug was introduced with commit ba3820ade317ee36e496b9b40d2ec3987dd4aef0
by Takashi Iwai. The result is that when using KMS my notebook's[2] screen
remains dark, because the backlight isn't turned on.

Reverting commit ba3820ade317ee36e496b9b40d2ec3987dd4aef0 makes my
notebook work correctly again as it used to in 2.6.38-rc8 and before.
