Ido,
That hasn't been our experience at all. After running into problems after upgrading our application, we were flat-out told by the good people at BO that the last version of the CR runtime that's supported on Win98 is 9.2.xxx. We even had to rewrite parts of our application to create the Viewer/Application/Report objects at runtime depending on the O/S. This has created other problems for us as well, so we're essentially being forced to drop Win 98 support for our application because of this.
