I've been Boxster shopping too...looks like 2005 was also a crossover year where early models have the serviceable bearing with the higher failure rate, the later models have the 06-08 bearing, which requires a teardown to replace.
My source is
Problem: IMS Failure. Solution: IMS Retrofit, lots of good data there.
