Hi Gabor,
I tried the latest cmpat-wireless 09-16 snapshot on my machine which runs on 2.6.31
Ubuntu Karmic latest kernel. The hardware probing passes and wlan1 interface shows up.
But the iwlist scanning got no data from wlan1 interface,
dmesg:

Do you guys think it is related to 64bit DMA issue? I really want to help to develop this b43 opensource driver,
anything need me to do, please feel free ping me.
Thanks
