general mechanical engineering principles would suggest that a service-able bearing should be replaced at a regular interval.

Good points. I asked Jake a while back what it would cost to replace the M97 IMSB. He said approx $4K. That's about the difference in current price between an 08 and 09 CS.
Trimer - As Jeff said, Porsche used to replace the blown engine with a new one. However, the new engine contained the same flawed IMSB as the previous one, so the crap shoot started all over again. Many Porsche dealers are now authorized to do the LN replacement.
