Linksys LNE100TX isn't recognized on boot

I'm running 9.0 on my file server and just swapped my NIC in an attempt to solve a problem with "too much work at interrupt". The new card is a linksys lne100tx. Kudzu seemed to detect it OK after the swap, but the only way I can get my eth0 interface running is to go into YaST, open the DSL config tool and let it run through the DSL configuration initialization procedure. Otherwise the eth0 network interface setup fails when I do 'rcnetwork restart'. After the DSL trick though, 'rcnetwork restart' works as expected. Anyone know what's going on here, and how I can configure my server so that the eth0 initializes properly during boot?
