According to http://www.syslinux.org/wiki/index.php/MEMDISK and
http://ubuntuforums.org/showthread.php?t=1549847&page=13&p=10818457#post10818457
it should be something like:

	# Boot super grub2 disk from iso image
	LABEL super grub2 disk hybrid_2.00s1-beta6.iso
	 LINUX memdisk
	 INITRD super_grub2_disk_hybrid_2.00s1-beta6.iso
	 APPEND iso bigraw

(but I haven't tested this.)

 I think grub-mkrescue(1) is for creating grub isos... (comes with grub2.)
