I have worked out a fix for this particular problem, it has been applied
to NetBSD-current, and it will be in NetBSD 1.6.1 (whenever that ships).

In short, the "disk1" image is missing the Sun disklabel that the PROM
needs to determine how to boot from the media.  So, we need to add one.

I recently added instructions to:
which document how write a Sun disklabel suitable for making the
NetBSD 1.6 "disk1" image bootable.

In summary, gunzip the attachment I've provided and write it to
the first sector of the floppy on which you've already written the
"disk1" image to, using something like:
	dd if=floppylabel of=/dev/rfd0a

If you want to permanently "fix" the disk1 image, use
	dd if=floppylabel of=disk1 conv=notrunc

Please let us know how that works for you.
