I agree with Richard.

Jochen, can you please try the following configuration (step #5 in my 
previous e-mail) ?

#auto eth0
iface eth0 inet manual

#auto eth1
iface eth1 inet manual

auto br0
iface br0 inet dhcp
bridge_ports eth0 eth1
# the wpa-iface option is expected to instruct wpa_supplicant
# to setup the wifi link using eth1 instead of br0.
wpa-iface eth1
wpa-driver wext
wpa-ssid ##SSID##
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk ##PSK KEY##
# The wpa-bridge option is expected to instruct wpa_supplicant
# to listen on br0 instead of eth1.
wpa-bridge br0

And if this fail, please try the same configuration, without the 
wpa-bridge option.

If both fail, please provide the list of files in /etc/network/if*/*.

	Nicolas.
