Why do the Catalyst Drivers not work well with kernel 3.2.9-2?

I had kmod-catalyst drivers working on Fedora 16 x86_64 and the update yesterday of kernel 3.2.9-1 to 3.2.9-2 caused a regression. With the new kernel I get random bursts of what appears to be static scattered across the entire Display screen. sometimes it is large rectangular hashy dark graphic noise mixed with single-line streaks of white. It works otherwise normally. It's obnoxious.

Not a fix, but can you try the open source drivers.

The kmod-catalyst drivers are just the ATI drivers packaged neatly for Fedora. It is known that ATI's support for Linux isn't any where near satisfactory. As @bodhi.zazen suggested, you could try the open drivers. They are constantly improving. If you want to continue using the catalyst drivers, please file a bug with ATI, there is nothing Fedora (or anyone other than ATI) can do about their closed source drivers.

One possibility is that you didn't receive a kmod-catalyst update to match the kernel update. Check on this. For every kernel update, you need to receive a corresponding kmod update. If this is the case, an update should fix it. The kmods lag the kernel updates by an hour or so generally due to mirror syncing lags.
