    I don't like using percentages here - we end up with the potential for
    several percentages to end up mapping to the same P state. I've sent a
    patch that replaces the percentage code with just stepping through P
    states instead. But otherwise, yes, this seems sensible. An open
    question is whether we should be doing the same on _PPC notifications.
    There's some vague evidence that Windows does.
