Yuo can run a 2.4 domU with a 2.6 dom0.  For that matter, you could run a 
FreeBSD, NetBSD or Plan9 domU too.  The virtual device interface is OS 
independent.

You can't boot with LABEL= syntax unless you use an initrd.  Yu cuold make a 
new initrd (do "man mkinitrd" for more info) or you could just specify the 
partition you boot off (e.g. probably /dev/hda1 in your case).
