Fedora 18 will be the first release that works well with NetworkManager 
and bridged networking.  However, I'd caution you that if you add both 
eth0 and wlan0 to a single bridged interface and connected your Ethernet 
cable, it's likely that your wifi would also be active some of the time. 
  In that case, you will have created a network loop which will cause 
broadcast storms and probably an outage of the entire broadcast domain 
that you're connected to.

I'd strongly advise against such a configuration.
