Not that it counts for much, but the NIC works fine in the vista install
that it came with.

That fails spectacularly with 'eth0: PCI Bus error 0290' after I do the 'up'
Someone suggested that the PHY isn't being detected.
I don't get any of the MII messages from rtl8139_init_one()
Which is odd (to me at least) as ethtool reports MII as a supported port,
(and even has it as the 'current' port).
