I agree - the ac_power check should be delegated to the scripts in the
event.d directory - after all, the suspend is _going_ to happen anyway,
apmd_proxy can't stop that, so it should simply pass this info on to each
sub-script.

I think it just means that apm support should be available, either
compiled in or in a loaded module. I don't think it really matters if
there is no APM support, since the kernel won't resopnd to APM signals
from the hardware, which therefore won't proceed with the suspension. [1]

It _should_ be sufficient to check for the existence of, and possibly
parse the contents of, /proc/apm.
PS: section 4 - isn't that the section of the metal health act that you
can be, well, sectioned under? Or is this a reference to something else?
