I ran across a site the other day that had a 3550 switch. They put "no switchport" on the interfaces and then added a bridge-group on the interfaces to bridge the traffic. It was at a site for the company that was purchased by the company I work for. All the network design and support was farmed out to ATT before we took it over, so there is really no one to ask what was the rational behind what they did.
Any one want to take a stab at why you would do something like this?

You can create different bridge-groups and assign them to the interfaces
based on how you want to create the broadcast domains. Something like:
bridge 1 protocol ieee
bridge 2 protocol ieee
!
interface Ethernet1/0
bridge-group 1
!
interface Ethernet1/1
bridge-group 1
!
interface Ethernet1/2
bridge-group 2
!
interface Ethernet1/3
bridge-group 2
I haven't personally used the 7200 simulator but this would work
for a regular router.
