Wii U hacked and CPU clock speed revealed, apparently.

I understand that this hack was most likely done using homebrew in Wii mode. Does anybody know if the WiiU is capable of scaling the clock speed up and down (similar to how modern processors do to save power when not under load), and if so, does it clock itself lower in Wii mode then in native WiiU mode? I wish Nintendo would just release the official specs.
