That's a typo in the DS manual. The DS model supports P-TTL with A- series lenses, no problem.
Pre-A series lenses used on the DS, DL, K100, K110 and K10D all do the same thing: the flash operates in full output, unmetered mode. You set exposure by using the guide number table in the manual. Only the *ist D supports TTL flash metering with pre-A lenses, and from what I understand, it isn't all that accurate. If you were going to buy anything more sophisticated than the Vivitar 285 or Sunpak 383, buy either the Pentax AF360FGZ or AF540FGZ. Personally, I haven't yet seen the need ... I use the Sunpak 383 and get excellent results from it.
