I've also got the feeling that Ukitake will sacrifice his life for the sake of Soul King. I don't know, maybe give his life force to resurrect the King or something. The Kamikake thing gives me the impression that Ukitake is intrinsically linked to Soul King. (Maybe he is sick because of part of his life belongs to Soul King)
