Just a followup - it was suggested this might be a hardware issue -
I've now run memtest86 for 9+ hours and 20+ passes with no errors.
The problem appeared when I upgraded from the old netbsd-4 branch
to -current just before the hackathon.

I'm guessing it's due to the RAM constrained nature of this system
(only 128 MB) that's bringing out this issue. I also just booted
a kernel without MULTIPROCESSOR, and was able to quickly crash the
system with the same backtrace.
