I think TestSleep has gone the way of the dinosaur: it makes calls on  
components that have never really existed except when there was  
random 1.x code in the 2.x repository. In theory, power management in  
TinyOS 2.x should (at this level) be automatic.

An app that does something similar would be Null.

I'll take a look. Chances are that some pins are not in the right  
default configurations.
