I would think that you could just use LABEL=, UUID=, or /dev/disk/by-uuid/foo.

Those device names only work on the kernel boot line if you're using
an initramfs, but I suspect that they'd work fine in fstab regardless.
 Situations like this of course are one of the reasons initramfs is so
popular - they can be far smarter about finding the root filesystem.

Disclaimer: I'm using an initramfs, so I can't vouch for what happens
without one.
