I did some structured tesing:

1. WOL does _not_ work at all when I do:
	(grub) boot into initrd
	(initrd) modprobe forcedeth
	(initrd) ethtool -s eth0 wol g
*	(initrd) poweroff

2. WOL does _not_ work at all when I do:
	(grub) boot into initrd
	(initrd) modprobe forcedeth
	(initrd) ethtool -s eth0 wol g
*	(initrd) Alt-SysRq-O

3. WOL works using the _un-reversed_ MAC when I do:
	(grub) boot into initrd
	(initrd) modprobe forcedeth
	(initrd) ethtool -s eth0 wol g
*	(initrd) Alt-SysRq-B
*	(grub) halt

4. WOL works using the _reversed_ MAC when I do:
	(grub) boot into initrd
	(initrd) modprobe forcedeth
	(initrd) ethtool -s eth0 wol g
	(initrd) exit
*	(Debian) poweroff

If I do the poweroff from linux (either initrd or Debian), forcedeth
seems to display some messages just before poweroff. I'll try to get
hands on a Serial-USB-Converter and a NULL-modem-cable to capture it,
since my laptop is legacy-free :-(

PS: initrd is actually initramfs, before somebody wonders.
