No, the "Face of the Enemy" webisodes revealed that Baltar told Gaeta "I know what your Eight did."

To explain, in the webisodes, it's also revealed that Gaeta was sleeping with an Eight on New Caprica, and had been giving her lists of people to get out of Cylon prisons. In reality, she was killing most of them, which Gaeta subconsciously repressed, though he kind-of knew it.

But yeah, that was a good episode, certainly - though if the teaser for Friday is right and Adama and Tigh are killed I'll be quite upset.
