Writing the latter might be a good idea, but in any case, the former
is easy, if a trifle slow:

	nm /vmunix | egrep 'T start'

which will give you the entry point (needed below); then

	cd /tmp
	cp /vmunix v
	strip v
	dd if=v of=vmunix bs=32 skip=1
	rm v
	arff rvmf /dev/crl vmunix

You can then

	>>>LOAD VMUNIX/ST 0

and

	>>>ST <entry>

where <entry> is the entry point found by nm, stripped of the high
bit (e.g., 80001614 => 1614).
