This is NIC doesn't appear to be plugged in.

Why do you want both interfaces to be configured on the same subnet?

This is probably expected behavior. What does "netstat -rn" show? My guess 
is that the route for 192.168.0.0/24 is "link#1" aka bge0 and since it's 
not plugged in to anything that's as far as it gets.
