Since my original posting I found a posting by Pelican.

Below are their findings.
The engine number of my 2001 Boxster S with a 3/2001 build date is M96 21/ 671 09227. According to a Pelican Technical Article, this engine should have a double row IMS baring.
The class action lawsuit states that single row bearings have an 8% failure rate while the double row has a 1% failure rate.
