Power Off At Shutdown (shutdown -p)

[Rishi Chopra]

I'd like to have my computer shutdown without pressing a key to reboot - 
'shutdown -p' doesn't seem to be working for me...

I have:

apm_enable="YES" in /etc/rc.conf, and
device          apm0    #Kernel config entry

Hardware is a Dell XPS120c - do I need anything enabled in BIOS?  Is 
there a way to check hardware compatabilty (e.g. something other than 
google groups, which isn't turning up anything)?
