Perhaps we've got version skew.
I'm using -current, and the following _works_, I just tested it.
	# dd if=/dev/zero of=/dev/rfd0a bs=512 count=512
	# disklabel -r -w fd0a floppy3
	# newfs fd0a
	# installboot netboot.sym /dev/rfd0a

The resulting floppy boots and attempts to initialize my network card.
If you are using something else (1.4.2?) perhaps the netboot.sym that
is generated by "make netboot.sym" is different.  I'll test it on my
1.4.2 machine in a few.
