Don't know if it's a "Debian thing" or not, but my setup is the same 
- eth0 will get renamed to peth0, and a bridge created called eth0.

That looks just like mine.

This is just a bit of a hunch, but if you are still having the 
problem, can you do this :
At the other network device, run "arp -an" and see what MAC address 
is reported for the device (Dom0 or DomU) that's pinging it. Do this 
twice, when one is working, and when the other is working - the 
entries you are interested in are the ones for the IPs of your Dom0 
and DomU
Also, I assume you have checked that the Dom0 and DomU are getting 
different IPs haven't you ?
