VLAN routing and bridging problem on a c2600 usig IRB

I've got a workstation that I want to connect to a remote host through two c2600 routers. The workstation knows its IP address and netmask only so I must use VLANs. I created a subinterface (fasteth 0/0.1) of the ethernet port and put it into a bridge-group. I also created a subinterface (ser 0/1.1) of the serial 1 but I can't put in into the same bridge group that the ethernet interface is in. The only serial port I can put into the group is the 0/1. It seems to me that it's impossible to bridge these two subinterfaces. The serial interface that I can bridge is the 0/1 only? I want to use the subinterfaces for VLANs but I want to keep the ser 0/1 as well. Is it possible? Here is the config:

bridge irb

interface FastEthernet0/0
ip address
speed 100
interface FastEthernet0/0.1
encapsulation dot1Q 32
bridge-group 1

interface Serial0/1
bandwidth 128
ip address yyy.yyy.yyy.yyy
bridge-group 1
interface Serial0/1.1
ip address zzz.zzz.zzz.zzz

bridge 1 protocol ieee
bridge 1 route ip

What's still missing?
