With the latest kernel 3.0.0-1.fc16.x86_64 I have problem with nouveau driver.
With previous kernel all work fine, I have good resolution (1440x900 for my laptop ), the desktop effect with kde work.

With this kernel 3.0.0-1.fc16.x86_64 I have a 640x400 resolution, and desktop effect don't work.

In the Xorg.0.log I can see :
