This is not a b43 problem. The standard loading of mac80211 sets an FCC regulatory domain, i.e. b/g
channels 1-11. You need to load mac80211 with a parameter of 'ieee80211_regdom=64'. That will allow
b/g channels 1-13. Technically, it sets the regulatory domain to Japan, but channel 14 is not allowed.
