I don't know that disks do, but an ext2fs filesystem has a unique number
(Filesystem UUID from dumpe2fs) which could be used to do what you want. You
could have a mounting program which examined every partition on every disk
it could find for a known partition type, and then found a UUID where
available, and mounted accordingly. This doesn't sound pretty.
