Another class of devices, but the Compaq OOM management cards for
servers ("RILOE") used to do this.  Really nice when the serial number
is placed on a sticker on a PCI card...  You would usually have to shut
down the server and pull out the card to read the sticker.  Unless it
had fallen off.  Did I mention that the cards had a number of stickers
with similar numbers on them with no indication which was the real
serial number?

Well, I'm not going to claim this was the reason why there is no Compaq
anymore, but it must have cost them *a lot* in support and frustrated
users.  For what passible gain?  It was still a default password, just a
tiny bit more obscure.
