No, the preference name MUST NOT start with protocol name. (see
prefs.c:579)

And the prefernce can contain only lowercase letters or digits or dot or
underscore. (see prefs.c:562)

Try:
prefs_register_uint_preference(mikey_module, "udp.port", "UDP Port",
"UDP Port (default 4369)", 10, &mikey_udpport);
