	Looks pretty sane. To confirm, you have /dev/sd0a mounted on /mnt
	(or whetever), have netbsd & boot in /mnt and have:
		cd /usr/mdec
		cp xxboot sdboot
		disklabel -B sd0
	Then halted, and a 'b' will get you to the first stage, but then
	chokes.... Hmm -  what does: 'ls -l /mnt/boot' and 'md5 /mnt/boot'
	give?

vaccination# ls -als /mnt/boot
31 -rw-r--r--  1 root  wheel  31480 Jan 21 22:29 /mnt/boot
vaccination# md5 /mnt/boot
MD5 (/mnt/boot) = bb236c3b481a7c2c131c731f59fc580f
