I don't think it is peculiar to Saab. I have heard (although not seen) about similar problems on some Toyotas and Audis made during the same period.
The theory I lean toward is that it has something to do with the PCV system (my car had two failed PCV valves before the problems showed up), in combination with short distances driven in cold weather.
The timing chain tensioner is a good thing to keep an eye on. Easier to take out and inspect/measure than pulling the valve cover, and you can tell if there is excessive wear in the timing chain and guides before the engine starts making noise.
