[Oneiric][cherry-pick-request] i915 native backlight

Kamal Mostafa-2
Please cherry-pick commit aaa6fd2a004147bf32fce05720938236de3361d9 from
Linus' master branch.  This patch fixes the backlight brightness keys
functionality for a wide range of laptops, see:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/568611
https://launchpad.net/~kamalmostafa/+archive/linux-kamal-mjgbacklight/+packages

This is a clean cherry-pick onto Oneiric master-next.

Thanks,

 -Kamal

    Not all systems expose a firmware or platform mechanism for changing
the backlight intensity on i915, so add native driver support.

Given the long standing nature of this bug, positive test feedback, and
a 1.5yr effort to get this patch upstream, I've gone ahead and
cherry-picked and applied this to Oneiric master-next.  I munged the
commit message to include the BugLink.  Kamal, I also took the liberty
to add your SOB.

Thanks,
Leann
