Yes, they were to deal with laptops that have a ton of levels, so you
want to smoothly go through the levels. So if you have a 1000 levels
switching from 10% to 20% shouldn't be a large jump, it should be a
gradient.

I believe that the patches were submitted upstream, though not applied
(we have a few of those). They were rewritten a couple of times to make
them more palatable upstream.

FWIW, the patch works well here for me on my Macbook Pro.
