powerd doesn't decrease CPU frequency in some cases

[Andrey]

Hi,

Thank you, Aragon.

Actually, your patch does the same as mine (but in a different way).
Thus we have at least 2 cases so far when the challenge is appeared.

But I'm not sure if our solutions are the best way out.
And... I believe, that it would be wonderful if Nate Lawson take a look 
here and evaluate the things we are talking through.
