With the loopback being gone it is _much_ easier to have the 
distribution network scripts setting up the bridge because the setup can 
look the same no matter whenever a xen kernel or a native kernel has 
been booted.
And have the bridge setup explicitly wired up in the distro 
configuration is much better and cleaner than playing tricks with device 
naming IMHO.  That way you don't confuse the distro network setup tools. 
 Also more advanced setups involving vlan and other fancy stuff are 
much easier to handle then.
Thats why I'd like to see all device naming tricks being dropped.

cheers,
  Gerd
