Just this morning I had to use the reverted address to wake up my
desktop PC after 6 hours of poweroff.

Yesterdays tests were domething like the following:
	Grub: Linux "loglevel=9 ignore_loglevel break=modules"
	dmesg -c > /dev/null
	modprobe forcedeth
	dmesg
	ethtool -s eth0 wol g
	echo NMAC > /proc/acpi/wakeup
	reboot to Grub using Alt-SysRq-B
	Grub: "halt"
I have to reboot back to Grub, since doing a "poweroff" from initrd or
pressing Alt-SysRq-O seems to turn of WOL.

Will try.

This is the new BIOS.
