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 !
