Yes, the stock CPU can run at 5MHz at least. I haven't tested it on my latest incarnation of test setup so I don't have fine resolution on when it dies.
I could see how much more is in the tank for a stock cpu. I actually don't think it is worth it to use the Tundra 8MHz chip because the rest of the system runs out of steam.
