While that is true, the current version of apm_emu.c is heavily
dependent on via-pmu.c. It would be nice to make it a little
more generic so that the features that can be used on other
models could be exposed. That's a fair amount of work.
Unless you want to make it generic enough to apply to all
non-x86 systems, it's also not very worthwhile to put a ton
of effort into this. If you want that, it's probably better
to take the official APM driver and split it into a front
end (just the device node stuff) and a back end (hardware
interface) so that anyone can write a new back end.
Any non-PMU Mac has only minimal power management. The cuda
based models have some stuff around scheduled powerup and
server mode and can reboot the box using a cuda command.
Older models can do poweroff and (in most cases) a clean
reset but not much else.
I'm not sure what your goal is. Do you just want X to shutup
about not being able to open an APM device?
