I believe this is an arp problem.  One might have to go around to all 
the other boxes on your network that keep track of such things, and all 
of them should, and find and delete the entries in each of the other 
machines arp tables so that the new MAC address can be inserted without 
the address clash its creating now.

And thats as close to telling you how that I can do because its been >1 
years since I had to do that here at home and I didn't make a consious 
effort to commit the exact details of it to long term memory in my 
ancient wet ram here.

Another possibility might be to give this newer card a different ip 
address, but that would require updateing the hosts files across your 
network too.  I'd prefer not to have to do that myself.

People having trouble with vz bouncing email to me should add the word

stupid bounce rules.  I do use spamassassin too. :-)
