The software itself is not bogus - it is designed to help you find drivers for Windows 7, Windows Vista, and Windows XP, which are not in beta testing. You landed on a page that is trying to help you find drivers for those systems. The bottom line is that if the latest drivers at Link Removed do not work for this device under the Consumer Preview version, you will have to wait to see if newer unified AMD drivers that come out will support Windows 8 for your graphics card. Right now, you really cannot expect any driver support when the OS itself is in beta testing.
You are in an unfortunate position whereas this line of graphics card was actually designed in 2002. This is about one year after Windows XP became commercially...
