When I did that, I had neglected to remove the patches I had made to the
ffs file system.  So the results were skewed.  Sorry about that.

I just built NetBSD again in a separate source tree, where the only change
made was "#define DEV_BSHIFT 11" (in i386/include/param.h).  Here's what I
should have reported:

boot device: wd0
root on wd0a dumps on wd0b
mountroot: trying msdos...
kernel: integer divide fault trap, code=0
Stopped in pid 0 (swapper) at   bounds_check_with_label+0xdb:   divl
%ebx,%eax
db> _

Not quite as kewl, but something about that function name seems vaguely
familiar...

(hint: line 511)
