The current drives do not work - they never had under linux, so they will not continue to work - where is my working video overlay, where is working rotation, where is working multi-monitor and above all where is the stability. So many bugs with the later r500 models (i.e. what I have) that its not even funny. Coincidentally, 9.2 borked and I had no video output on my system. I had to go back to 9.1.
I cannot and will not remain with an old os - and why should I. It DOES LOOSE SUPPORT because newer Xorg and Kernel upgrades will bork the driver. Maybe you can't seem to understand that some of us need the new features that come out - even be it just stabilized support for other hardware in later releases of the kernel.
I've been hearing about the promise of opensource drivers for too long. That carrot-on-a-stick routine is way too tiring now. Already waiting 2 years and now told to wait even more for a working driver is not acceptable business practice IMO.
