Hi Freddie,

I don't know if my shell fu is good enough, but I have multiple bridges working. 
I posted about it quite recently:
<http://article.gmane.org/gmane.comp.emulators.xen.user/33926>

In short, I created a custom network script:

# cat /etc/xen/scripts/my-network-script
#!/bin/sh
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0
"$dir/network-bridge" "$@" vifnum=1

... which is then used by xen:

# egrep -v "^(#|$)" /etc/xen/xend-config.sxp
(network-script my-network-script)
(vif-script vif-bridge)
(dom0-min-mem 196)
(dom0-cpus 0)

.. and in the domU:s I just use "bridge=xenbr0" or "bridge=xenbr1". Very simple. 
 No requirement to assign IP addresses to the dom0 interfaces.
Good luck!
