Wake on lan for skge or forcedeth

I have machine that I need to be able to wake up from the network.
It has 2 network interfaces:
- "nVidia Corporation CK804 Ethernet Controller (rev a3)"
using the forcedeth driver.
- "Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 13)"
using the skge driver.

For both of them `ethtool' tells me that wake-on-lan can be enabled to
reply to MagicPackets ("g"). If I try "ethtool -s ethN wol g", the "wol"
state is properly set to "g".

But if I then turn the machine off, no amount of "etherwake" seem to be able
to resuscitate it.

After a reboot, the wol state of the nVidia interface is always reset to
"d", but not so for the Marvell interface.

The BIOS doesn't seem to have any setting that may affect wake-on-lan (the
motherboard is an ASUS A8N-SLI Premium).

Does anybody have an idea what I might be doing wrong?
