Ok ICMAN, step back and look at this from a different perspective ...
I want to believe that the problems are all ATI's fault as much as you do, but maybe, just maybe it is a combination of things that are specific to CMR2, and none of your other games.
Are you using any other hardware specifically for CMR2 that you aren't using for any other game? What hardware are you using to play CMR2 (I suspect a gamepad/joystick/wheel that you wouldn't use on anything other than a racing sim)? There is a strong possibility that it is either this hardware or the combination of this hardware + Radeon that is the cause of the lockups, and that it won't happen with other games since you don't use that hardware for anything else. If this is the case, verify that the controller does not share the same IRQ as the video card (or maybe even the sound card?). At the very least, disable the controller and try just the keyboard and/or mouse (this will suck, but if the game doesn't crash, then it isn't the Radeon). If it crashes, then you have eliminated another potential cause, and will have more of an argument that it is ATI's fault.
If you aren't using any additional hardware, disable sound, lower graphics settings, upgrade DirectX, close background apps, etc, and eliminate all other possibilities.
HTH, and I am really sorry that you are having these problems.
