Steven, I don't know whether this has any relevance or not, but I recently 
changed a NIC in a FC4 box, and initially had a problem.  It seems that it 
had detected the card correctly, and was loading the driver, but it had 
remembered the MAC address of the old card.  I had to remove the card's entry 
in system-config-network, then run kudzu to get the new card read in again.  
Since then I have had no problem.
