There was an example added to the xend-config.sxp file in the commit
which made these changes (I missed it at first too).

I don't think the references to "allow-hotplug ethX"  and "iface ethX
inet manual" are necessary. All that should be necessary is the "auto
xenbrX" and the "iface xenbrX ..." bits which you have. e.g.

[...snip unneeded stuff...]

It's also probably worth drawing attention to the interfaces(5) and
bridge-utils-interfaces(5) man pages.
