I'm running NetBSD 1.0 and similarly didn't want to try to integrate
the NTP stuff into the kernel.  Instead, cron runs ntpdate periodically 
(ntpdate is a utility that comes with NTP, but doesn't require the 
kernel support).  Ntpdate fetches the time from an NTP server.  Works OK.
I have to run it every 5 seconds to keep the time within +/- 500ms
of "real time" due to crummy PC clocks; but there's no noticable 
overhead.  (If you keep the time drift within +/- 500ms then the
"real time clock" will slew rather than jumping when corrected.
