no, i'd still keep a sharp eye on this thread and not rely too much on the "official" NF7-S thread. chances are, if you haven't already found your answer in that thread, nobody's posting in there anymore. all of those official threads have gotten hundreds of replies within the first week of being posted, and have been stagnant since. i.e. you'll be lucky if anyone sees your question behind 500 other posts.
in reference to your problem, were the nVidia drivers you downloaded made for linux? if you don't know, and nVidia doesn't offer specific drivers for specific OS's, that doesn't necessarily mean you downloaded universal drivers. make sure nVidia has a disclaimer stating this.
