Hmm let me lay it out for you:

I was like you a year ago when I had my fan speed too high. I mmiotraced
proprietary fglrx driver and proposed a patch for this. Alex said that time
that reverse-engineered patches are not welcome upstream (various licensing
issues, I suppose) and suggested to pull a set of initial patches for handling
fan control through AMD IP bureaucracy. I agreed.

This took around month or even more, IIRC. These shinies are not sort of things
so easy to get from large corporation. In the end Alex handed me over these
patches and I was able to fix typos and implement fan control for SI and CI
cards.

I can do it for r600, but again, I will need patches of same kind and moreover,
working BARTS GPU in St. Petersburg where I live to test and debug it.
