I can't really speak for AMD/ATI, but I ran the NVidia binary driver from their website for a while in combination with Debian Testing. In my experience, the driver had to be reinstalled every time the x packages were upgraded, not just X versions, but packaging changes as well. That was really unpleasant as it occurs quite often. Not downloading a new driver, just reinstalling the one you already had. Luckily, I can now use the Debian packages for the binary driver and nouveau is also good enough if I don't run 3D heavy applications. So maybe just try to reinstall the AMD driver?
