MFC of r270516 to enable brightness adjustment in i915 systems

Since the introduction of the Intel Core series with integrated GPU (Sandy
Bridge, I think), more and more people report that they can't get the
brightness to adjust. This has been reported on a variety of units and was a
problem on my ThinkPad T320.

It turns out, this is fixed in HEAD and my brightness works just fine, either
under program control or with the <Fn><Home> and <Fn><End> keys that are marked
as brightness controls.

I have tried applying the same patch to 10-Stable and it works fine for me and
at least one other person who has tried it. Since 11 is way down the road, I'd
love to see this make it into 10.2.

Could some committer please take a look at this one? The revision is 270516.

The patch for 10-STABLE is included in this report.
