I always figured that Tom Bombadil, though he appears in human form to those who may see him, is a manifestation of the spirit of "indifferent nature". Maybe that's too harsh a word, since Bombadil is portrayed as a kindly soul, but the affairs of humanity just cannot touch him.
Elrond said something to the effect that if Sauron prevailed, then even Bombadil would fall, "last as he was first". But I don't believe this. Earth, and Tom, would abide. Maybe in a form that humans would not recognize or be comfortable with, but that would mean little to him.
(Don't know if I'm making myself clear here. I'm typing against the clock.)
