hostapd + bridge

Hi,
I am using a Debian based system called "c't-Debian-Server" with an integrated
IPCop firewall running in UML mode (User mode linux). The phsical network
interfaces are connected to IPcop using tun/tap devices. IPCop's "blue"
interface (for WLAN) is connected to tap2 with IP 192.168.254.1 within the
UML. Now I want to set up a WLAN-AP with hostapd and connect it to br2.
Without bridging it works just fine with hostapd and WPA, but after adding my
wlan-interface to the bridge and setting up the bridge there is no connection
anymore. Are there any ideas out there?
Here is what I've done:
> brctl addif br2 ath0
> ifconfig br2 192.168.254.100
> brctl show
br0 8000.0040f4cdaa34 no eth2
tap0
br1 8000.00e07dc449fa no eth1
tap1
br2 8000.ee254d91a3d9 no ath0
tap2
br3 8000.fa63a7d1bcde no tap3
> ./hostapd /etc/hostapd/hostapd.conf
