Maybe a limitation of legacy_kernel.
Normally to use labels in grub2 the 'search' command is used without any 
reference to the device assignment.
Like:-

menuentry 'Mageia-2 multiboot' {
search --no-floppy --label --set=root mageia-2
multiboot /boot/grub2/i386-pc/core.img
}

&gt;<i>
</I>&gt;<i> menuentry 'Cauldron defkernel' {
</I>&gt;<i>    legacy_kernel   '(hd0,22)/boot/vmlinuz' '(hd0,21)/boot/vmlinuz'
</I>&gt;<i> 'root=LABEL=22cauldrn' 'splash=verbose' 'noresume' 'video=1152x864'
</I>&gt;<i> 'vga=794' '3' ''
</I>&gt;<i>    legacy_initrd '(hd0,22)/boot/initrd' '(hd0,21)/boot/initrd'
</I>&gt;<i> }
</I>&gt;<i>
</I>&gt;<i> It works when I s/hd0,21/hd0,22/g.
</I>&gt;<i>
</I>
That syntax is apparently correct, as legacy_kernel needs to know what 
the original legacy command was.
I have tested here in a clean mga3 installation and it works for me.

Please re-test and if it fails again please attach the original menu.lst 
and the resulting grub.cfg along with any error messages.
