As an interesting follow-up, I noticed that the kernel doesn't seem to 
handle math very well. Commands "ping" and "top" crash as well, and ping 
yielded an interesting message: "math_emulate: 0xd9fa not implemented
Illegal instruction", which points to the kernel option that is supposed 
to handle this. I did enable "options math_emulate", but old posts on the 
netbsd lists seem to indicate that the emulation is or was not complete 
at one point. This may be my problem since ntpd probably does a lot of
statistical calculations. I'll post there and see what people say.
