That isn't going to work. eth0 is the needed to provide the tagged interface, the eth0.x are just pseudo interfaces that have tags. You can bridge the vlan's but unless you do filtering with ebtables to restrict what flows why bother? If you do bridge a bunch of vlan's then the original eth0 interface on the bridge should be left alone. If you need the bridge to have an IP address assign it to the bridge pseudo network device (br0).
