I was discussing with Elisabeth back in this blog post about the above problem, and made comments that there were no plans currently to backport this to SQL 2005 or 2008. This changed following feedback both from customers and from us within CSS, and the fix was made part of SQL Server 2008 SP1. You'll note if you look at the KB article for SP1, that it doesn't have it's own KB, but it does get a mention in the fix list.

Enjoy!
