Wii U CPU + GPU clock speeds increased? Is it even possible?

[UncleScrooge]

Didn't those guys who measured the Wii U's CPU clock speed say something along the lines of "maybe it was simply downclocked for the menus?" What if the CPU *always* ran at 3.2 GHz in-game and Nintendo simply upped the *menu*-clockspeed for faster loading times? Is this possible?
