Use APM in -STABLE/-RELEASE, ACPI in -CURRENT. Not guaranteed to work, but
the APM implementations on desktops are generally less bug-ridden than those
in laptop BIOSes.

The sheer number of ways that the ATX power supply signalling pins can be
connected to the southbridge or SuperIO chip in most machines would boggle
one's mind, which is why the BIOS deals with that sort of thing.
