My first thought, Does swapping the wires fix this? Crude maybe, but it 
should work.

Then I thought "oh, you might need to attack ifcfg-eth0 and ifcfg-eth1 
to delete the MAC addresses."

Now, I'm thinking that running system-config-network to swap the 
definitions so that eth1 is the gateway to the world and the other's 
private.

That should work, and continue to work over time.

I had  half-hearted fiddle with opensuse 10.2 on my laptop (wireless and 
wire, i want the guest on the wireless) and didn't get anywhere.
