Sony PSP underclocked and RAM mismanaged?

According to Kotaku Sony will make a patch available to developers that will unlock the processor speed, giving the game you're playing full access. After the game is over, the processor cap will go back in place to help conserver battery life. The speed must have really been a big issue. I wonder what kind of battery life you would expect if the whole this was permanently unlocked. It would be bad enough that Sony would have to cap it. Kotaku also notes that the Sony PSP's OS gobbles up 8 megs of the available 32 megs so developers only have 24 to work with. ouch.
