Hrm... On 2.4, it's not that simple, there can be 2 keywest controllers,
one on the northbridge, one on the southbridge, driving various parts.

With 2.6, these will be visible in sysfs once i'm done with the porting
of pmac drivers to the new model.

I'm not sure I like the idea of having drivers tapping things on those
i2c busses if those drivers aren't specially designed for the pmacs. I
hate the idea of something preventing proper cooling of the machine and
thus causing HW damage, or around those lines...


Ben.
