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?

Cheers,

Nico
