You still need to verify that this is the MS driver. The RIM document might not explain how to confirm but I know you can search here or Google it. Just because Vista selected a driver automatically doesn't mean that it used the MS Bluetooth stack. Every version of Windows ships with a number of drivers for various manufacturers.
In general, when troubleshooting it's best to minimize the variables involved. Tossing Vista into the mix probably wasn't the best choice but I think it should work. Good luck with it.
