Please refer to the information on wireless.kernel.org:
http://wireless.kernel.org/en/users/Drivers/brcm80211#Regulatory_Implementation

You could investigate whether the NVRAM/SROM country code is indeed 
blank or really configured with 'US'. For the driver itself channel 13 
can be used as long as your access point is transmitting beacons, 
because it is regarded as a passive channel.

Reading the logs listed in bug #622842 I would suggest running the 
following command after loading the brcm80211 driver:
$ iw set reg EU

You should see following in the log:
Apr 30 10:05:22 myhost kernel: [ 3967.072332] cfg80211: Calling CRDA for 
country: EU
