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?
