Spare ethernet card prevents thin client from booting

[Greg Reagle]

I have experienced an Edubuntu server (version 6.06 I think) with two
Ethernet devices that is not consistent about which one it calls eth0
and which one it calls eth1.  I don't know whether this inconsistency is
at the BIOS level or the kernel level.
