Sorry for the late intrusion into the conversation, and perhaps it's a bit unrelated, but given that you're creating a 'VF assignment management' perhaps it's the right place to add some sort of mechanism in order to prevent module removal once one of its VFs is assigned. [e.g., incrementing module reference count] At the moment [to the best of my knowledge] there's no mechanism preventing the 'not-so-bright' user from removing the driver, and no good will come out of it.
