KB919598 (http://support.microsoft.com/?kbid=919598)  has been recently updated to reflect the fact that all management packs affected have now been published to the Web with updated reports. There is no longer the need to contact Microsoft Customer Support Services (CSS) to obtain fixed reports which had not yet been published.

The last two remaining MP's which now have updated reports which successfully import against SQL Reporting Services 2005 are the Exchange 2000/2003 MP and the Virtual Server 2005 R2 MP.
