The daemon (ntp) seems to start, but it won't accept any connections.  
After booting a clock-box I have to log on, stop and restart ntp.  This 
later, manual, start works, leaving nothing in the logs to explain why ntp 
is not working.  I suspect ntp is trying to locate network interfaces, and 
they haven't come up, yet, when ntp is getting started.  I use Via 533 Mhz 
C3's for clocks, mostly, and udev takes a long time to report stuff like 
an interface coming up. 

Since ntp always starts manually, and I rarely shutdown or start a box 
running pps, I've ignored the problem.

Of course, the fact that this has happened on boxes running linux 2.4 
and ntp 4.2.4p6 - and I never had the problem in past years with ntp on 
thoses boxes- really suggests ntp has a problem.
