You can assign different IPs to the two NICs if you use DNS aliases to point to both. That way if one goes down, the DNS will look at the other IP. This'll only work with publically routable IPs or NAT. AFAIK you can't assign the same IP to two different NICs on the same network as it'll cause problems. If you are talking about a fail-over solution for a server that's only on your local network, I don't know the answer :)
