I researched, tested, and toiled for countless hours burning the midnight oil and have solved some issues in the last legacy driver for 4000 series and below for anyone who wants to make use of them for legacy cards, Vista/Win7 x64 only. I'm using these homebrews myself because movie transcoding is important to me, as is the correct 4870x2 clocks at idle desktop broken since 12.2. I wrote a seperate application to reset the multigpu clocks elsewhere on the forums, but using it is no longer necessary if you use these repackaged drivers. http://www.mediafire.com/?txspkpbdloanuzp MultiGPU clock bug with 12.x series kicked into the abyss, broken GPU assisted movie transcoding works again amongst other problems/quirks solved. ATI tray tools functionality restored. Still a WIP, but everything working and tested as it should work at least on Win7 x64. Complete well rounded package including latest CAP profiles for legacy cards, nothing else needed. See readme file in package.
