As you guessed, it is not a bug as support for that device has never been 
enabled. I think your device will use bcma just as my BCM43228 does. I have 
started developing the patches needed to implement it with b43; however, I have 
not gotten very far. Could you please confirm that the the PCI ID is 14e4:4358? 
If that is correct, could you also try the attached patch and report the info 
that is logged in the dmesg output?

I think that Broadcom will be changing brcmsmac to support these devices, but my 
understanding is that they are concentrating on fullmac devices at the moment.

That is correct. The bcm43227 is very similar to the bcm43228, the
difference being the supported bands. I have not heard back since I
forwarded your questions on 43228 support in brcmsmac. So for now I can
only say that bcm43227 and bcm43228 will be added in one patch.
