Yes. bcm4331 was/is on our TODO list, but when b43 added support for it we were unsure how to move forward. > I do not think it is a big problem if brcmsmac supports some chips b43 > also supports as b43 misses some important features, for now some > devices IDs for devices supported by brcmsmac and b43 they are > deactivated in b43 by default so brcmsmac is used every time.
