Can you also please try to change the order of the scanzas in 
/etc/network/interfaces, so that iface br0 comes before iface eth1 in 
the file ? ifup -a is expected to bring the interface in the order they 
appear in the file...

Also, you could add "bridge-fd 0" in the br0 stanza. Because you bridge 
is by design loop-free, there is no reason to wait 32 seconds before 
entering the forwarding stat.

'hope this helps.
