Not sure how much time you've spent on this, but at some point I reckon it is better to stop spending time on it and get a definite answer.
To find a definitive answer and resolution, you can call Microsoft Support directly. I've done it a number of times when the issue is urgent and could not wait, or when spending more time on it was not a wise choice.
If you call, it is a $259 call, but they'll definitely resolve it for you, to your satisfaction...
If you email, it is $99, and if you can effectively communicate via email, that's a good option too.

If you go this route and end up finding a great way to distribute the SSRS ActiveX Print Control, please let us know what they give you as a solution. I'm about to deploy SSRS 2008, so I'd like to know what Microsoft says, if you call...
