Well, 100 points for you! rmmod of b43 and bcma and modprobe of b43 afterwards restores the ability to connect! Btw, I've found another issue: The signal level seems to be set to 0 for all networks, thus wpa_supplicant does not select the best network (Follow the white rabbit! in my case). Thus I've used "select_network 9" to force connection to the right networt. Log attached below. So, what are the next steps to debug/fix this issue to make me (and probably everybody else with a macbook pro 8,1) happy after suspend?
