One of the things that's missing in this discussion is where ACPI fits
into the grand scheme of things.

ACPI is *NOT* the correct way to implement MI power management.  Instead,
we need a higher-level power management API.  ACPI would be just one
back-end to that high-level API.

It just seems silly to say "ACPI ACPI ACPI!" when so few of the supported
NetBSD platforms will actually *have* it (and would thus have to emulate
it, a pretty gnarly task).
