Sorry for being unclear.
To use 802.1d briging you need kernel 802.1d bridging support compiled 
in, AND bridge-utils from http://bridge.sourceforge.net/ .

Then you need to create a bridge interface by:

brctl addbr br0

and add the interfaces you want to bridge to the bridge interface:
e.g.:

brctl addif br0 eth0
brctl addif br0 eth1

next you have to disable the bridged interfaces by:

ifconfig eth0 0.0.0.0
ifconfig eth1 0.0.0.0

additionally you can assign an address to the bridge interface, if you
want your box to be reached over this interface (which is strictly 
against OSI-model because bridgeing is on ethernet level, which doesnt 
know about ip adresses, but it works an is useful).
After a few minutes of learning mode, the bridge will be up and working.

p.s.
The above can also be found in the README files of hostap-driver and 
various other howto's on the net :-)
