  I move my Debian and Ubuntu hard drives from my computer at home to
a couple of computers at the local computer club.  What I found is
that I have a configuration for each different location in the
/etc/network/interfaces file.  All I did was copy the one from my
home machine using DHCP setup and then labeled them eth1, eth2, etc. 
I have no problem at all.  I think that the ethx is based on the MAC
address.  A different eth for each MAC address.  I've never moved the
card with the disk from computer to computer to test my theory
