Yup, that's been tried as well.  Along with switching the port
on the Ethernet switch.

My "last resort" is taking the 3Com card out of the machine in the
den and swapping it with one of the Netgear cards in the server.
My "last, last resort" before I start debugging the device driver
for the card is adding Yet Another NIC and seeing if two of the
three work.  But that's just too twisted to even consider right now.
