Bug Description

Kernels up to 2.6.30 had all the windfarm modules needed for G4 and G5 iMacs cpufreq and fan control:

/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_core.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_cpufreq_clamp.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_lm75_sensor.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_max6690_sensor.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_pid.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_pm112.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_pm121.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_pm81.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_pm91.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_smu_controls.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_smu_sat.ko
/lib/modules/2.6.30-2-powerpc64-smp/kernel/drivers/macintosh/windfarm_smu_sensors.ko

However, in 2.6.31, only windfarm_core is available. Thus, at every boot, the fan speeds up and is very noisy, and the cpufreq isn't clamped correctly, possibly leading to overheating.

Please compile the windfarm modules for 2.6.31 too.
