I've ran out of time to do this today so will have to come back to it
tomorrow but the routing on a machine on both sides of the bridge is
just a normal default route and the device doesn't have a route setup

 $ /sbin/route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     *               255.255.255.0   U     0      0        0 eth0
default         192.168.0.254 0.0.0.0         UG    0      0        0 eth0

I agree that this should all work so it is probably just something
daft. I've built the physdev module and got it installed but not
tested it yet, hopefully that will solve things.

Are there any basic tests anyone can suggest that I can work through
to try to debug this?
