I wonder why doesn't our current linux loader fail gracefuly and tell user
to use linux16.  I thought we had code specifically to do this!

  if (! (lh.loadflags & GRUB_LINUX_FLAG_BIG_KERNEL))
    {
      grub_error (GRUB_ERR_BAD_OS, "zImage doesn't support 32-bit boot"
#ifdef GRUB_MACHINE_PCBIOS
                  " (try with `linux16')"
#endif
                  );
      goto fail;
    }

  /* FIXME: 2.03 is not always good enough (Linux 2.4 can be 2.03 and
     still not support 32-bit boot.  */
  if (lh.header != grub_cpu_to_le32 (GRUB_LINUX_MAGIC_SIGNATURE)
      || grub_le_to_cpu16 (lh.version) < 0x0203)
    {
      grub_error (GRUB_ERR_BAD_OS, "version too old for 32-bit boot"
#ifdef GRUB_MACHINE_PCBIOS
                  " (try with `linux16')"
#endif
                  );
      goto fail;
    }
