This already works, but it's unfortunately not quite flexible enough.
Here's the bridge stanza from one of my machines:

	iface br0 inet static
		address 10.20.30.40
		netmask 255.255.255.0
		bridge_ports eth3 eth4
		bridge_stp off

		# this is a Hack. ifup/down requires an IP for this interface even
		# though we don't want one, so we assign bullshit and remove it once
		# the bridge is up.
		up ip addr del 10.20.30.40 dev br0

ifupdown requires an "inet static" interface to have an address, but a
bridge doesn't always need an IP. I need to file a bug on this.
