You may want to re-download this one if you got it already, I just fixed
a bug in the calculations of the CPU control loop. It's now getting
results much more consistant with OS X. I still have to add some
overtemp handling and I'll remove the debug stuff and work on supporting
the PowerMac9,1 desktop model.

Ok, I've updated it. News are:

 - It now requires cpufreq support (it won't start if the cpufreq clamp
sensor isn't loaded). I also changed the Kconfig stuff a bit, you'll
need to enable 2 options now

 - It has some totally untested support for PowerMac9,1

 - It has overtemp support (will slow CPU down and blow fans full speed
if the machine goes overtemp)

 - It has some basic sysfs interface to read values
in /sys/devices/platform/windfarm.0

 - DEBUG is disabled by default

Enjoy !

Ben.
