Can you debug it yourself a bit? I cannot afford buying so much memory. ;)

In loader/i386/pc/linux.c, there is a piece of code like this:

  if (grub_file_size (file) > (grub_ssize_t) grub_os_area_size)
    {
      grub_error (GRUB_ERR_OUT_OF_RANGE, "too big kernel");
      goto fail;
    }

Can you see what is printed when you change this to:

  if (grub_file_size (file) > (grub_ssize_t) grub_os_area_size)
    {
      grub_error (GRUB_ERR_OUT_OF_RANGE, "too big kernel (0x%x > 0x%x)",
                  grub_file_size (file), grub_os_area_size);
      goto fail;
    }

Cheers,
Okuji
