For this I used another machine with a comparable setup, since I am at
the moment not at the first machine. It too has a Prism2.5 PCI Card
with the mentioned firmware.

I just tested with ieee8021x=0 and wpa=0 instead of ieee8021x=1 and wpa=2:
Same thing. ARP requests incoming on wlan0, but not showing up on br0.

I also tried it the other way round: If I try to ping the laptop on the
WLAN, I can see the ARP requests going out on br0 and then eth0, but not
wlan0.

It seems not to be a problem of encryption, then, but somewhere else.

This is without encryption.

brctl show:
bridge name     bridge id               STP enabled     interfaces
br0             8000.0010dcca8d5d       no              eth0
                                                        wlan0
brctl showstp br0:
br0
 STP is disabled for this interface

ifconfig (removed uninteresting devices (sit*, ippp*, lo)):
