findfs UUID=<uuid>

You can use `udevinfo --query=all --name=/dev/<partition>' to get the 
uuid of any partition. If a filesystem does not have a uuid, you can use 
`tune2fs -U random' to set a random uuid to that filesystem.

Simply use root=UUID=<uuid> in menu.lst and UUID=<uuid> instead of the 
partition name in your fstab
