No, don't know how to make it work (are you using a custom kernel by any
chance? I think that it needs kernel support).
I do know to answer the fstab part of the question though, fstab has nothing to
do with that part of the booting process. It is used by the init scripts and
mount. It's the kernel that needs to recognize the uuid values in order to boot.
