I can try just about anything on my G5. It exists strictly for testing, right

If you can point me to a .deb with the patch that I can install, I’ll be happy
to test it.
That code seems to be a G4 related item :

* Time-stamp: <2004/03/20 14:20:59 samuel>

* <therm_windtunnel.c>
*
* The G4 "windtunnel" has a single fan controlled by an
* ADM1030 fan controller and a DS1775 thermostat.
*
* The fan controller is equipped with a temperature sensor
* which measures the case temperature. The DS1775 sensor
* measures the CPU temperature. This driver tunes the
* behavior of the fan. It is based upon empirical observations
* of the 'AppleFan' driver under Mac OS X.
*
* WARNING: This driver has only been testen on Apple's
* 1.25 MHz Dual G4 (March 03). It is tuned for a CPU
* temperature around 57 C.
