lspci says that the builtin ethernet on nVidia nForce3 chipset is a
Bridge.  It should be a Communications device.

This specifically was a problem on planetlab2.icu.ac.kr, but there
were a few others as well for which we worked around the problem by
inserting a known-to-work NIC card.

With this little special exception we basically treat this device as a
network device and can therefore use this NIC.
