In my case, the UUID in menu.lst matches what the entry in /dev/disk/by-uuid links to my root filesystem.
BUT... /etc/fstab refers to filesystems by the much more sensible (and memorable) /dev/hd* names; I think because I edited it back that way after an earlier upgrade. I'll have to try putting UUIDs back in and see if it makes a difference.
I'm sure there must be a reason for Ubuntu's insistence on using UUIDs rather than /dev/hd* names, but I'm sure it's outweighed by the inconvenience - after all, what's easier to remember, /dev/hda1 or c9593a22-7236-4321-9fe3-a5187ed87c53? I know which I find easier.
