+1 I am a fan of the Sheldon Brown method. If I am thinking right, you will have to access the bolt from INSIDE the bottom bracket. So I would use a socket, a short extension, and a 1/2 inch breaker bar. I would soak with Kroil a couple of times. If that did not work, I would bring heat into play, and still use my breaker bar. Once the cup is hot, I think it should come out.
