Yeah; I knew (or was pretty sure) that it was down to the chip level at this point, but as you say, for driving the price down, there's nothing like the single-chip solution, and this is apparently just far enough off the edge of the popularity curve that it's not in any single-chip solutions (that I know of, and board-level hardware isn't really my game).
