Having the apm module should be enough (unless you want to use ACPI).
You might have to modprobe it manually or add it to /etc/modules. If
your power-off does not work, check with "lsmod | grep apm" if the
module is really loaded.
If it does not work even with the APM module loaded, you might have to
enable CONFIG_APM_REAL_MODE_POWER_OFF. Quoting from the help text for
this option:
Use real mode APM BIOS calls to switch off the computer. This is
a work-around for a number of buggy BIOSes. Switch this option on if
your computer crashes instead of powering off properly.
