Yes, we've had Wake-On-LAN (WOL) support for about two years.
for a basic web page describing some details.
For the discussion below I'll assume that you are asking about 3Com PCI

The 3c905B and 905C generations both have WOL for twisted pair media types.
(Errrmm, well, perhaps not for 100baseT4.)

For the 3Com cards you'll need 3c59x.c v0.99L or later, in their original
versions. Modified versions of the 3c59x.c have not been tested, so I
suggest that you start with an original driver from
Some chips power up ready to do Wake-on-LAN. The 3Com chips do not, so
you'll first need to boot the target machine and load a driver that
explicitly configures the chip into WOL mode.
You'll also need the 'ether-wake' program from
This wake-up program must be installed on the controlling machine. It won't
do much good on the machine that's asleep.

After loading the driver on the target machine, record the Ethernet station
address in the detection message. Shut the target machine down and do a
soft-power-off. Do not switch power completely off with the power supply
switch, or the card will lose its WOL configuration.
>From the control machine run something like
[root@vaio log]# ~becker/diag/ether-wake 00:50:04:7c:6e:8c
with the correct station address for your card.
This will turn on the target machine.
[[ Yes, the exact line above just turned on a Abit BP-6 motherboard with a
3c905C plugged in with a WOL cable. ]]
