    450 interrupts/sec sounds ok for an idle system.  I'd expect a higher
    number, actually.

    I wonder if the load calculations are being messed up by the C3
    state.  The code path for the per-cpu hardclock interrupt has always
    been fairly sensitive.  With the 8254 it was being driven by IPIs.
    Now it is being driven by an actual interrupt so there might be an
    issue with how it distinguishes the system state when accounting for
    the clock tick.
