Is Buffett vulnerable in the current AIG probe?

Berkshire shareholders don't seem to think so -- the stock hasn't suffered much, and the Buffett premium surely represents a huge chunk of the stock's value. Still, the news that he may have been involved in setting up the controversial non-insurance transactions whose investigation cost AIG's Greenberg his job isn't exactly swell. I think he's probably too popular to lose his position -- this isn't a flash-in-the-pan kind of adulation; Buffett-worship has been a popular cult for over a decade.
