There are some detail changes, like the larger IMS bearing, but other than that you would be hard pressed to find any differences between them. In '07 they went to 3.4L and Vario Cam Plus, which would be a little harder to deal with, but likely still doable.
Seeing that your '03 S and the '06 S both used ME 7.8 engine controls, you should not have issues, with the one exception being that the '06 uses and extra solenoid to control a valve on the intake T. The "fix" is to simply use the intake from the '03, which is interchangeable.
So, use the long block from the '06 with your existing harness , engine controls, and exhaust, and most of the rest from the M97 would work (should be most everything short of the intake T) and you should be good to go.
If I were to look for a stock engine replacement for my '03 S, I would definitely look at an '05 or '06 M97. Then again I would probably get a late (three chain) 3.6 M96 or M97.
While the engine is out, I would also swap in the 987 airbox.
YMMV
