http://wiki.freebsd.org/TuningPowerConsumption/ says LAPIC timer stops when CPU in C3, while I saw the flag is set to 7. Of course, I can read full spec and code (http://fxr.watson.org/fxr/source/x86/x86/local_apic.c?im=bigexcerpts#L251) to find out some processor's LAPIC timer runs in C3, but mailing list could be helpful to get some quick answer.
