Don't let xen automatically configure your network adapter. The
autoconfig stuff is great if you boot between xen and non-xen
configurations, but if you are always using xen just do it yourself.
Configure the bridge as part of your init (eg /etc/network/interfaces
under Debian) and put your IP addresses etc on that, and then comment
out any reference to 'network-script' in /etc/xen/xend-config.sxp.
