Funnyyyy... So I went out and grabbed some disks, even a SMO-C501, a
MicroScience 660MB/SCSI 1, IBM 0663 and a Seagate Barracuda 32550N, and they
all worked with SYS_INST - that is, disklabel recognizes them and reads the 512
bytes. Haven't tried writing the label with all of them, though. With or
without terminator, of course 8-)  Wierd....
