That is what I kind of thought...

Put:

if_bridge_load="YES" in /boot/loader.conf.

You can also load the module with:

kldload if_bridge

IIRC, your settings in rc.conf should be enough to configure the bridge,
 so if you choose to load dynamically while running, try a
"/etc/netstart" to configure the bridge.

If that doesn't work, a reboot should.

If you can't get it to work, supply the same output I asked for above,
and then I'll set up a quick lab here to test it.
