Why revoke the old one? If I want to send a message I don't think needs 2048 RSA bits of security, why bother with it? I have little doubt the FBI would get your key from your computer at 1024 bits. Thus, the effort needed to compromise a key does not change as one moves from a 1024 to a 2048 bit key. Threat models are really helpful. They become more helpful as one acurately assesses ones enemies. Ronald Kessler wrote a book called The FBI. Its fairly evenhanded examination of the post-Hoover bureau. He does gloss over DT & Waco; they occured as he was finishing the book. Reading it will give you good insight into the way the FBI, and its agents, work.
