This works! Thanks for this work. :-)

Observations:

A trivial bug:

                        count -= bsize;

Installboot has no hp700 support and disklabel doesn't interact well
with this boot code. I.e. disklabel overwrites parts of the first stage
boot loader. To get a first stage boot loader onto the disk with a
disklabel I did this:
$ cp sdboot /tmp/sdboot
$ grep '^ a:' /root/dl.sd0
 a:    264192  0     4.2BSD   1024  8192 32856  # (Cyl. 0 - 191)
$ disklabel -rR sd0 /root/dl.sd0
Make filesystem on /dev/rsd0a, put "/usr/mdec/boot" and "netbsd" on it.
$ dd if=/dev/rsd0c of=/tmp/sdboot bs=512 skip=1 seek=1 conv=notrunc
$ dd if=/tmp/sdboot of=/dev/rsd0c bs=512
and now disklabel(8) doesn't recognize the disklabel on the disk
anymore. Seems like it checks more as it should. 
$ reboot

The disk is now bootable. The bootloader / kernel doesn't get the
correct root device. So I used "-a" at the boot prompt and entered "sd0"
when it asked for the root device. Unfortunately a kernel bug stoped
further progress.

I'll now try to get sdboot, boot, disklabel(8), installboot(8) and the
kernel into sync.
