Additional Information
OLD WORKAROUND:  If the ifcfg file is created before entering into the 
YaST plugin, the unconfigured card can now be configured.  IE:  touch 
/etc/sysconfig/network/ifcfg-eth1
Restarting the network has not been bringing up the interface, even
 after it is configured (rcnetwork restart).  Manually bringing up the 
interface with ifup does work (ifup eth1)
