Do you have an /etc/iftab?  Does it tie some other MAC to eth0?  I found
that after a fresh install, my real NIC's MAC was tied to eth1 and eth0 was
tied to a MAC that consisted of the first half of the real MAC for my
wireless NIC (which is really on wlan0, anyway).  I just commented
everything out of there, and now it works fine.
