I'm not sure what "make it more reasonable" is telling me.  In subject
line and commit log, please say something more specific than "the
proper places."  

It's probably more important to say where they are moving *to* than
where they're moving *out of*.

Is the power savings the *reason* for this change?  I can't tell from
the commit log.
