It seems that PPC Macs have a hardware PMU: http://www.resexcellence.com/linux_icebox/01-31-02.shtml And that some embedded devices handle this at the hardware level with no OS support needed: http://ozlabs.org/pipermail/linuxppc-dev/2001-February/010179.html So AFAICT there's no standard like ACPI - each board does it differently.
