Well, we know that there's at least a PP5024 and PP5024B (I think it's a B) in the E200 which doesn't have the video capabilities that the Advertising Flyer says it has. Another revision could exist.
But that is a very good point. Once code's running on it, one could conceivably attempt to reach different clock speeds and see which of our current targets it behaves the most like (at what point does it become unstable?)
It's hardly scientific, but it is a test.
