I guess not. At least in this machine changing the backlight works
correctly, whereas in v3.11-rc3 it was all weird, and v3.7-v3.10
didn't work at all. I cannot see how it would affect negatively other
machines.

That being said, the blacklisting is still needed, because 1. the
level is not preserved between boots, and 2. level 0 turns off the
screen, which I personally consider a regression.

At least it boots to level 100 instead of 0.
