well we are using 2 bridging firewalls too, although we do our failover through (abusing) spanning tree. ie. wee create an artificial loop with both firewalls, due to the spanning tree algorithm one of the firewall's interfaces will be deactivated (and activated again if the other fails). there is no heartbeat and no additional scripting required :-) works really nice for us - YMMV.
