I guess I must have just been lucky, then.  Having twice recently turned 
a Windows server into a Linux (=Debian) server, my experience is that
the hardware that used to jump around tens of ms and hundreds of PPM
converges to a couple of ms in a few hours and stays there; having decided
on a drift value, it tends to stick with it.  I've yet to build NTP for
Linux.  I just fire-and-forget, straight from the distribution.
