i think it's the combination of these two factors:

- bootup frequently is typically full-speed, so we calibrate things
right

- cpufreq events are relatively slow-scale - and when they trigger the
system is definitely not under load. So how precisely the scheduler
functions isnt all that important in such scenarios - there's tons of
CPU power available.

but it's indeed nice to have this fixed, and i just pushed the fix to
Linus.
