OK, you seem to be actually interested in solving what is now evident as
a hard problem.

The tool I used to develop and test WoL is 'pci-config'
You can get it from
   ftp://ftp.scyld.com/pub/diag/pci-config.c

[[ Hmmm, there is actually a newer version, but the only changes are for
the Operton. ]]

This code allows reading the PCI configuration space registers.
I use it to monitoring if the card is trying to raise a wake-up sign.
It has an extra piece of code expecially for the 3Com chips enabled by
    --set-WOL 
With this you can
  Find the board index by running 'pci-config'
  Run 'pci-config -#<INDEX>' to see the current board state
  Test that ether-wake triggers the PME (Power Management Event) bit
  load, start, stop and unload the driver
  pci-config -#<N> --set-WOL
  test again to see if  ether-wake triggers the PME bit.
