Hm, I just gave powernowd a go. It has an interesting idea of gradually sliding the CPU speed up and down instead of stepping by hundreds of megahertz like cpufreqd does. On the other hand, it only cares about CPU load, and doesn't change CPU speed depending on the power source, etc. And it didn't actually seem to lower the CPU speed according to "cat /proc/cpuinfo", nor in /sys/, but it does (according to strace) seem to be writing to the correct locations. > 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.
