Three things come to mind.
1) Engine Timing chain - possibly the tensioner weak
2) Engine Counetr balance shaft drive chain - there have been reports of the sprockets wearing out and allowing chain noise.
3) Accessory Serpentine drive belt pulleys - these are known to wear out about every 40,000-60,000 miles. The usually make a rattling noise as they near the end of their life.
Your best bet is to have a mechanic familar with the Saab engine listen to the sounds and try to determine whether it is excessive or normal.
