I don't know that I'd lump Carmack in with the rest of your list. Yes, he is quite financially successful from id, but he never stopped being, first and foremost, a coder who will sometimes just disappear for a few weeks to separate himself from the world and get coding done.
I wouldn't list Jobs either for almost the opposite reason in that while he had a huge impact on the tech industry, he was always a "suit" (even if he didn't wear one).
