That's why I wrote a patch for Debian's bridge-utils that even was
included sometime later and allows for the following, avoiding exactly
this last-mentioned problem:

    auto br0
    iface br0 inet dhcp
    	bridge_ports regex (eth|vif).* noregex

(See bridge-utils' documentation.)  Perhaps this should be mentioned in
the Debian Xen documentation?
