I've been playng with the tickadj command, and am currently set
at 9926, default is 10,000. And I'm keeping pretty good time now.
Running ntpdate in slew the clock mode, once per hour, I'm
logging this now:

So while its not perfect, its adequate.

As to whats doing it, I have NDI.

Thanks, I set it to 9942 and checking with ptktime and it's looking good, before it was drifting by 3 seconds by this time - with 9926 it was losing slightly, 2 secs in about 5 minutes. On the laptops and the Mandrake box that are rock solid it is set at 10,000, the P-II/333 laptop is using the SuSE 9.2 kernel and the others are on 2.6.10-rc3.
