Yes, I agree, and my question is only on what you mentioned: "it didn't want to load an optional image" maybe I misunderstood the above, never mind, :-) So one driver should suppose the firmware is there, and the firmware shouldn't be zero length, because the driver always expects getting some bytes by calling request_firmware().
