    I have to use the max_cstate=2 option to processor.ko in order to not
    have a similar high pitch noise. I suppose you might get away higher
    values of max_cstate depending on your hardware. Battery life doesn't
    seem to be too adversely impacted.

    Hmm... Which would do a better job at driving physicists crazy? Travel
    faster than light, or a floating-point boolean value?
