An update on my post above.  Disabling TurboBoost in the BIOS seems to have
resolved the issue.  I wonder if TurboBoost somehow causes mis-reported aperf
statistics.

Interestingly enough, the ratios are the same as the turboboost ratio on this
CPU.  That is, 3.2GHz (Turbo)/2.5 GHz (Stock) == 800 MHz (Real minimum)/625 MHz
(reported minimum via aperf).  I don't know if it matters, just thought it was
notable.
