In brcmsmac we reprogram the PCI BAR windows upon resume. Not sure if
that is done or needed in bcma, but may be worth checking.

Good point.

Please reload b43 *and bcma*. Both drivers. Share your results.

Well, 100 points for you!

rmmod of b43 and bcma and modprobe of b43 afterwards restores
the ability to connect!

Great! :)

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.

Sorry, you're probably missing two important patches:
b43: fill ctl1 word on all newer PHYs, fix PHY errors
b43: HT-PHY: report signal to mac80211
I believe both will appear in 3.2-rc3.
