The native package should work regardless of your chameleon build being 6900 series friendly or not (not many builds are that I know of other than ones that I have built myself or shared on here) so you have at least picked the right package.
Alright, well I will give it a try tonight. Would it make a difference if Windows is installed on a different HDD? Or that I have a couple of bootable backups of Snow Leo and Lion? I just always assumed no, but I figured I'd ask since I have your attention.
