You mean walking the filesystem in grub_efi_set_prefix ?  Humm, this looks
like a hack.  The filesystem may not be FAT and there may be no way to read
directory entries (eg tftp - even if not yet supported).

If you really don't like it I can put it away for now.  Grub should work
without this patch in most cases.
