Strage, at the moment I can't seem to reproduce the problem. I've
switched back to the version of and now it seems to work.
I'll continue with tesing.

Some additional data:
The BIOS-upgrade tool (Afud408.exe) resets the MAC address. I had to run
the tool a second time to re-programm the MAC-address using its /M
option. I useed the unreversed MAC-address back than.
I also tried the reversed address once, but after that forcedeth.c
complained about a wrong MAC-address.

If I completely turn off the power (pull the plug), WOL doesn't work,
even when it's enabled in the BIOS.

Only after I'v started Linux, do "echo NMAC > /proc/acpi/wakeup" and
"ethtool -s eth0 wol g" does it work again.

Nether the less here's the output of dmesg:
forcedeth: Reverse Engineered nFoce ethernet driver. Version 0.61.
ACPI: PCI Interrupt Link [LMAC] enables at IRQ 23
forcedeth: 0000:00:14.0: PCI INT A -> Link[LMAC] -> GSI 23 (level, low) -> IRQ 23
forcedeth: 0000:00:14.0: setting latency timer to 64
* nv_probe: MAC_ADDR_REV ELSE
nv_probe: set workaround bit for reversed mac addr
forcedeth: 0000:00:14.0: ifname eth0, PHY OUI 0x732 @ 1, addr 00:19:db:f2:e1:35
forcedeth: 0000:00:14.0: highdma pwrctl timirq gbit lnktim desc-v3
The line maked * was inserted by me in the source file for my debugging.
