Basic ELF (just text and data) isn't that hard to do.  Have a look at
the first stage pmax bootblocks in sys/arch/pmax/stand/scsiboot/bootxx.c
- the loadfile() function is what you want.  I've not yet really looked
at the mopd stuff yet, so I don't know how easy it is to graft in...

If you have a mop package external to that supplied NetBSD, you
could try just throughing the relevent NetBSD headers files into the
distribution.
