x86 specific nonsense. Apple laptops use (varying revisions of) a chip called
the Power Management Unit, or PMU. Hence 'pmud' for power management
functionality on Apple PPC systems. There are similar features for pmud (which
can be defined through /etc/pwrctl/pwrctl-local, iirc) to what you're talking
about for defining suspend/unsuspend actions. There is also some primitive
compatibility for certain APM-specific stuff (like XFree86's power management
awareness) that can be built into the kernel, but otherwise apmd is completely
irrelevant on any PowerPC system.

Heck, even x86 PCs are starting to abandon APM, though I'm not sure if the
transition to ACPI is for the better or not.
