In your case I would say b43 registers itself with phylib module and provides phylib_ops. It could also provide the bcma_device for the 80211 core so the phylib can use bcma directly. Whether or not phylib is still a library module when doing so can be argued. As it does not provide a system function by itself I tend to say it is. I would suggest to look into mac80211 to see how it deals with the callbacks it does into the device drivers. Gr.
