I think this a future way to go. For now I have something simpler which
only addresses the adt7460 and the adt7467. And it is tailored for
Powerbook/iBook only.

Hopefully soon :)

It'll look like this:

root at wolfram:/root # sysctl dev.adt746x.0.
dev.adt746x.0.%desc: Apple Thermostat Unit ADT746X
dev.adt746x.0.%driver: adt746x
dev.adt746x.0.%location: addr=0x15c
dev.adt746x.0.%pnpinfo: name=fan compat=adt7460
dev.adt746x.0.%parent: iicbus0
dev.adt746x.0.fans.rear_left_exhaust.pwm: 48
dev.adt746x.0.fans.rear_right_exhaust.pwm: 48
dev.adt746x.0.sensors.cpu/intrepid_bottomside.temp: 64.0C
dev.adt746x.0.sensors.cpu_bottomside.temp: 63.0C
dev.adt746x.0.sensors.pwr_supply_bottomside.temp: 57.0C
dev.adt746x.0.sensors.cpu_core.volt: 194
dev.adt746x.0.sensors.rear_left_exhaust.rpm: 2160
dev.adt746x.0.sensors.rear_right_exhaust.rpm: 2309

Unfortunately I have some stability issues. My PB freezes or switches
off under load. I need to debug a bit more. Might be my driver or the
Powerbook itself which has its age.
