Head was recently fixed so that brightness now works fine. The patch
applies cleanly to 10-stable (and 10.1) if you want to try it. My T520 has
had working brightness since. Yes, it works with the Fn+HOME and Fn+END
keys that are marked as brightness up and down on the keyboard. The patch
is to the ACPI code in dev/drm2/i915.intel_opregion.c, though small changes
were made to a couple of other files to enable access to the new code,

It's in head as r270516 and Adrian has thus far not MFCed to 10-STABLE. If
it works for you, you might let him know that you would like to see it done.
