I believe you have your partitions set up improperly.
Mine look like:
part'n 0: sysid 6 (MSDOS) : start 32, ....  (0:1:1) (c:h:s)
part'n 3: sysid 165 (NetBSD) : start 372736, ....

Note that I leave a whole track for the boot manager.  The secondary bootstrap
and disklabel stuff is done into your Unix "a" partition... that is, way away
from the beginning of the disk - in my case, 372736 sectors in.
What may be confusing you is that certain utilities will write "default"
stuff occasionally.  I personally goofed several times over not providing
-B to disklabel at the same time I am writing the label with the -w option.
I intend to write a doc on this one day.  In fact, it's almost done :)
