i can see the frequency change in /proc/cpuinfo. hmm... scaling on power source. that seems like a good idea. > > btw... where in /proc can i find the laptop hd/cpu temperature? there is no > > entry in /proc/cpuinfo and i set CONFIG_TAU=y (no AVERGE though) in the > > kernel build. > > You don't want tau on a ibook g4, you want CONFIG_THERM_ADT746X in the > "Device Drivers" -> Macintosh -> "Support for thermal mgmnt on laptops > with ADT 746x chipset" menu.
