Well, other models have an i2c fan controller that is supported by
hwmon, so I'm not sure it's necessarily -that- a good idea to change
that (but then I've never been a fan of hwmon either :-)

I'm half tempted to actually stick a thermal control kernel thread in
there and leave userspace out of the game too, like I do on most macs. 

I'll think about it. No time right now anyways.

Cheers,
Ben.
