I looked at the driver source code and there is certainly an attempt to

Please refer to the information on wireless.kernel.org:

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:
