If you have a switched network and place two NICs on that network with the
same ethernet address and different IP addresses you confuse the switch.

You can change the ethernet addresses of your qe0 by using ifconfig ether
or use setenv in OBP but I don't remember the exact parameter.

Yes that is true, but you were trying to route to the same subnet.
Configure qe0 to 192.168.0.9/24, connect it to the 192.168.0.0/24 network
and you should not have the reported problems.
