You see, if the p54* modules are compiled into the very bzImage: The instant workqueue option wouldn't work because the device might be initialized before the filesystem is. A combo approach [delayed workqueue, when no userspacehelper is available and a direct call to request_firmware (when it is availabe)] would work too, but then we would be reimplementing request_firmware_nowait ...
