So I don't have to have the complete path in fstab like this:

/dev/disk/by-label/boot        /boot        ext2        noatime        1 2
/dev/disk/by-label/root        /        reiserfs    defaults    0 1
/dev/disk/by-label/swap        none        swap        sw        0 0
/dev/disk/by-label/portage    /usr/portage    ext3        defaults    0 1
/dev/disk/by-label/home        /home        reiserfs    defaults    1 1

Can you post a grub.conf file that uses labels?  Sort of a example to 
look at and go by.
