And to give you a reason why I think they should plan for it: Windows XP SP1 is what they not only use on their own systems but also set as a requirement for developers to use with their SDK's (together with some custom packages and Visual Studio 6).
From my experience this is because the changes to DCOM security in SP2 break how they've written their applications. You can get it to work by fiddling in dcomcnfg yourself but this didn't seem to be something the Siemens guys had tried.
