Not by default: the apm device isn't enabled in the GENERIC kernel.

apm is required so that `halt -p', or preferably `shutdown -p' will be
able to power off your system. Your machine has to have an APM Bios
for this to work --- which is usually a feature of laptops rather than
ordinary PCs. Nb. it's better to use `shutdown' rather than `halt' as
that gives any processes running on the machine a chance to shutdown
gracefully and clean up after themselves.
