One quick point - if you still have a viable 'netbsd.old'
kernel in the root directory you can boot from it by pressing
SPACE during the boot blocks countdown, then type
'boot netbsd.old'.
The problem you are having is that your normal root filesystem is
not mounted when you type 'mv /netbsd.old /netbsd' - at that point
the root filesystem is the in kernel ramdisk.
You should not use /tmp as a mountpoint - if you need a spare
mountpoint then 'mkdir /mnt2' or similar and use that.
It sounds like you root filesystem might be very unhappy - can you
try: (replace wd0a as necessary)
fsck /dev/wd0a
mount /dev/wd0a /mnt
cd /mnt
mv netbsd.old netbsd
reboot
