I wasn't sure what you meant by "compare" fstab with /dev. I was surprised to see you recommend running ./MAKEDEV sd0 because that is exactly what hosed my system in the first place. I think you may have over-estimated my knowledge of FreeBSD. Anyway, going on your clues, I figured out that what I needed to do was to run './MAKEDEV sd0' followed by './MAKEDEV sd0s3a'. This created sd0s3a through sd0s3h, which is exactly what I needed. Now she boots up fine. Thanks very much for your help!
