Did you check the FIX article I referenced above (http://support.microsoft.com/default.aspx?scid=kb;en-us;2717598)? At the top of page there's a large green hotspot titled 'Hotfix Download Available'.

I can't say if this is the latest version but it certainly addresses the issue I had. Note that the downloadable hotfix is a re-release of the OLE DB Provider for DB2 v4.0 so you are advised to remove your existing installation before installing the hotfixed version.
