oops! have i left something out of kernel or kld load?

No, Michael's example was for old-bridge which is depreciated. You had
the config right.

Thanks Andrew! In reading
http://www.freebsd.org/cgi/man.cgi?query=if_bridge&sektion=4 it looks
like either

device if_bridge

or

if_bridge_load="YES" in loader.conf is all that's needed.

For testing purposes, you might want to disable the filtering
configuration with:

sysctl net.link.bridge.pfil_member=0
sysctl net.link.bridge.pfil_bridge=0

Regards,

Mike
