adjtimex adjusts kernel variables; the results will not be preserved 
across a reboot.

Write a tiny C program to call adjtimex and run it each time the system 
boots and before starting ntpd.  The amount you need to put your clock 
within 500 PPM should be more or less constant and ntpd should be able 
to correct for any minor variations.
