Well, I did the Atomic Wrangler quest, getting everyone availiable and passing all the speech checks, that got me a good bunch of fame. I then payed Garret 1000 caps to spread the word, and smooth talked the junkies in the High Times quest to get my status at Freeside to idolised. I guess the Kings have stuff to also raise your fame, although I haven't done any of their stuff yet.
