The problem I see with that is that these things are generally settings that people might want to change dynamically at runtime so you really want to be able to change these things via controls like everything else about the configuration. If they were just fixed and unchanging in a system then request_firmware() would be a good mechanism that's a bit more modern than the ioctl.
