+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
+}

+> 'vga=794' '3' ''

+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.
