This was reverted in commit 7383123647566, but reverted when a
Chromebook Pixel (2015) regression was reported.
Jani wrote a patch to fix backlight, but that one has been completely
ignored by the original reporter of the bug.
We now have more testcases for fastset, so it should be possible to
enable with some confidence about regressions.
