Historically, the powermac suspend-to-ram code has been it's own
separate entity (existed before there was some global system suspend
framework in the kernel). It has never been "merged" with the core
suspend code in that sense that it's not hooked to /sys/power/state.
This will eventually happen in the future, but for now, sleep is
triggered by it's own ioctl sent to /dev/pmu, either by the snooze
command, or by pmud or pbbuttonsd.

I think there are some conflicts.
