Note that i've started doing work on the SMU driver yesterday as the
iMac G5 finally came back from Apple. I have the fan control pretty much
figured out, and I'm still working on figuring out the access to the
various sensors and i2c busses.

A call graph of Apple kext would still be useful tho, and if somebody
manage to figure out how to also get some sense into the c++ vtable
method calls (map them to method names), that would be awesome.
