Oh, so you've missed the emails where people say its shit? ;-)
Look for the emails of Daniel Lezcano who has been working on better estimating the IRQ periodicity. Some of that has recently been merged but it hasn't got any users yet afaik.
But as said before, I'm not convinced the actual idle time is the right measure for NOHZ, because many interrupts do not in fact re-enable the tick.
