Umm, MS has a program that allows Dev's to certify their own drivers for FREE. Above that there is a program where for a small fee, much smaller than before, that MS will test and digitally sign the drivers. I also believe that only the self certification, which MS leaves up to the Dev's to be honest, is all that is required for x64 Vista due to the kernel restrictions which on Windows IMO is a great thing. The task at hand for the Dev's is for all of the developers to simply make their drivers x64 vista compliant to within MS's guidelines and then self sign them.
