I have a hunch that this is the problem. Have you tried 2.6.27 without the proprietary ATI drivers? This is the first thing I would suspect because ATI drivers are not reputed --- or so I believe --- for being the best quality software out there. Either way, we need to eliminate as many factors as possible and one of these factors is your ATI driver change. I don't know much about Prime95, but if it won't simulate a subtlety in your video drivers, especially how proprietary ATI drivers will play with kernel 2.6.27.
