Well unloading the driver seems a bit clumsy, and a contradiction really. (unloading a driver to use hardware). I would add the flash ROM functionality to the NIC driver, and have it export an MTD map. The space.c stub implementation would just return EBUSY if the interface is up, but specific drivers could enable interleaved access as they are able.
