But I have found no mention of this specific dual-bridge problem I have: that ip traffic goes in ok through any physical nic to the dom0 or domUs, but all replies are routed to only one nic (the default gateway). (I verified this with tcpdump.)

That's not xen or bridge related. Unless you do policy-based routing, packets always follow the destination route regardless of where the input was received. That's a feature, not a bug.
Ok. But this error does not occur on my other CentOS 5 box (mailserver, non-xen) which also has 2 nics for 2 public ip segments. There input-nic is always = outputnic. And I have done nothing special to achieve this (pure "linux magic"). That's why I "blame" bridges - they are the most notable difference between these two machines.
