It's the calibration that is so delicate ---
the calibration tries to map the amount of
instructions you run to the amount of elapsed
time the PIT shows. If this is unstable, the
calibration will take a LONG time!!
OTOH, once the system is running, it won't try
to compare times anymore so there's no problem
--- okay, all your timings will be wrong, but
you're unlikely to notice this unless you have
some very delicate hard-realtime hardware (perhaps
CDR burners would be affected ?)
