It looks like you have to recompile the kernel to get that feature. I
use kernel-image-2.4.4-1 (supposedly unstable package ported to
potato) and it does not seem to have apm support enabled.
root@ping:~# apmd
No APM support in kernel
"dmesg" doesn't show any apm related messages. Yes, I could recompile
the kernel but I really don't like doing that when I administer a
large number of not very identically configured systems. It seems to
be very inflexible having to recompile the kernel just to get
poweroff to work.
