ath client bridge

Hello
I have problem to setup bridging box with ath in client mode and if_bridge
When card is in AP mode, everything is ok, but if I want to run card in
client mode, bridging is not working.
Here are my testing steps: (it's quite long, so I prefer put URL there :) )

It seems to be ath related problem, or am I doing something wrong ?

My second question is why chipset 5213 is detected as 5212  (ath0:
<Atheros 5212>)?

Thaks for help and reply
