Well, basically put all options you had in config_eth0, routes_eth0, ... into 
config_br0, routes_br0 and so on.
in your case its prolly config_br0=("dhcp").

don't forget to rc-config add net.br0  after creating a net.br0->net.lo 
symlink in /etc/init.d

the bridge "inherits" the MAC of the first eth device attached, so the dhcp 
client should be able to get the IP config just fine.

for the xen config: I havn't disabled the network / bridging scripts there, 
those are smart enough to not foobar the config when the bridge in question 
is already up. Not sure if there's a problem in disabling them.

I haven't found any usefull documentation for Xen/Gentoo yet, but also didn't 
have a reason to look for one.
I've basically choosen that way cause my desktop box, where I tried xen first, 
already had a bridge fully configured and running for use with bluetooth pan, 
and I simply reused that bridge for the domU.
