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
