I haven't rebooted again to check whether my laptop is varying processor 
speed, but it's quite probable - so this explanation is plausible and fits 
my observations.

I think a warning about laptops should be included in the FAQ(*), and it 
would be a nice touch to have a  warning when the service is about to be 
started for the first time.  Also, if the BIOS can be queried to established 
whether processor speed is set to fixed or variable then this could be used 
by ntp to block the service.

Anyway, it has been a lot of needless hassle.  Surely, there must be a whole 
bunch of people who have been down this path before...?


* I searched for laptops in the FAQ but there is no mention in sections I 
deemed relevant.
