(I haven't followed all of this thread so apologies if it's already been
covered)

You do have the correct brouting rules in place don't you? eg:

ebtables -t broute -A BROUTING -p 802_1Q -i eth0 -j DROP

This makes sure that the 802.1q tagged packets coming in on eth0 are not
sent over the bridge as is, but are 'routed' internally to the vlan
code, where they are decapsulated and then maybe routed to bridges.
