[Beowulf] WOL on nforce4 mobo under linux?

I had to change the /etc/init.d/halt script to end with
echo '5' > /proc/acpi/sleep
just before the 'exec $command' (which normally does the halt). Anyway,
bit of a hack but sends my machines to sleep where they can be woken up.
Just try above command from command line to see if your ethtool settings
are correct & acpi is functional.
