* kern/i386/pc/init.c (make_install_device): When memdisk image is
        present, "(memdisk)/boot/grub" becomes the default prefix.

        * util/i386/pc/grub-mkrescue.in: Switch to a minimal core.img plus
        a memdisk tarball with all the modules.  Add --overlay=DIR option that
        allows users to overlay additional files into the image.
