Trying bisecting didn't work for me, as (according to the wiki's translation of the output) it spans non-linear tags. My attempt to build from a 3.10 mainline kernel produced an image that suffered from the same issue, but that didn't provide a linux-image-extras package which seems to be necessary for the brightness controls to work.
