Hi Greg,
It sounds like the nic is working, just not making it out of the box.

what does "ifconfig -a" show for eth0?
what does "route -n" show?
can other machines ping that box? (i would expect this to fail if the nic 
cannot answer arp requests)

(is the cat5 cable good? I have seen damaged cables that displayed a link 
lite, but could not pass data)
