I followed the above instructions and this is the result;
Yewdales-lodge:~# modprobe apm power_off=1
FATAL: Error inserting apm
(/lib/modules/2.6.8-3-k7/kernel/arch/i386/kernel/apm.ko): No such
device [The file, apm.ko, is there, I checked.]
Yewdales-lodge:~# apm
No APM support in kernel

I suspect that the kernel has acpi enabled. You can check by seeing
if the directory /proc/acpi exists and is populated. To use apm,
you will need to disable acpi. You do this by passing the argument
'acpi=off' to the kernel, either on the grub command line or in the
grub configuration file, /boot/grub/menu.lst. (I'm assuming that you
use grub; with lilo the procedure is similar.)
