That's my understanding too.

I tried setting the partition label.
dumpe2fs -h /dev/sda13
dumpe2fs 1.41.10 (10-Feb-2009)
Filesystem volume name: <none>
Last mounted on: <not available>
Filesystem UUID: c2e3fa11-3ee5-41eb-a8e1-cc4c11c29044

e2label /dev/sda13 lfs-svn

and then using
menuentry "LFS SVN 20100627, Linux 2.6.34-label" {
linux /linux-2.6.34 root=LABEL=lfs-svn ro
}
But that was not able to mount the root fs. As you noted, fstab makes
no difference, because it can't be read until the root fs is mounted.
