Please consider cherry-picking this patch from torvalds/linux.git for
Oneiric:

    drm/i915: Fix inconsistent backlight level during disabled
    04b38670cf46c096705f24e92a8747d1ab89e53c

It applies cleanly, and fixes

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/872652
screensaver backlight stuck off, system looks hung

which affects a large number of users.  The patch is Cc: <stable> so
will land in Oneiric anyway, but it would be nice to get this one sooner
rather than later.
