Comment 2 for bug 677758

Maybe i'm misinterpreting it, but isn't that part the modules that get initially loaded after the grub memdisk image is loaded into memory (assuming they can be properly referenced at that point)?

The reason that the patch is working properly is because it's being included directly into the memdisk image (by the $4 argument):

    $grub_mkimage -O ${platform} -d "${source_directory}" -m "${memdisk_img}" -o "$3" --prefix='(memdisk)/boot/grub' \
        search iso9660 configfile normal memdisk tar $4
