Correct way of doing bridging is to create a bridge br0 and add *all* 
IP's  on the bridge itself (br:0, br:1, ....).

I am not sure, but it *might* allow you to add IP's on the *first* 
bonded device, but I am not sure about all of the later bonded devices.

Test somewhere first, and make sure you do "service network restart" 
each time.
