There was a change between suse 8.0 and 8.2, and I don't know if it 
changed in 8.1 to default to using acpi instead of apm.  My laptop did 
not support acpi.  I had to do the following to lilo for it to work. 
Check the append line for what I added. The kernel is stupid, and does 
not care who does this, but the first one loaded will be the one that 
gets to do your power management.  The APM or ACPI modules do handle the 
poweroff at the end of a shutdown, so this would be the likely culprit.

     label = SuSE
     root = /dev/hda7
     vga = 788
     initrd = /boot/initrd
     append = "acpi=off"
