If we don't change eval-buffer, we should fix Fload itself.
It has this code now:

  if (!memcmp (SDATA (found) + SBYTES (found) - 4, ".elc", 4)
      || (fd >= 0 && (version = safe_to_load_version (fd)) > 0))
    /* Load .elc files directly, but not when they are
       remote and have no handler!  */
[...]
  else
    {
      /* We are loading a source file (*.el).  */
      if (!NILP (Vload_source_file_function))
	{
	  Lisp_Object val;

	  if (fd >= 0)
	    emacs_close (fd);
	  val = call4 (Vload_source_file_function, found, hist_file_name,
		       NILP (noerror) ? Qnil : Qt,
		       (NILP (nomessage) || force_load_messages) ? Qnil : Qt);
	  return unbind_to (count, val);
	}
    }

Apparently, Fload doesn't intend to handle a compressed
byte-compiled file.  And, it is possible to bind
load-source-file-function to some other function than
load-with-code-conversion, modifing
load-with-code-conversion is not enough.
