Description of problem:
Whenever I try to boot without the "nomodeset" kernel argument (which is the default) the system freezes while starting X.org (the fedora logo on plymouth is full). If I use KDM I can even login but when I enable compositing (aka desktop effects) X crashes and the system freezes. The system also freezes if I try to enable compositing on Gnome or KDE with the nomosetset argument.
Version-Release number of selected component (if applicable):
This happened with all kernel versions up to kernel-188.8.131.52-145, with all the updates from updates-testing installed.
Steps to Reproduce:
1. Boot without "nomodeset" as a kernel parameter.
The system freezes and a hard reset is required.
The system doesn't freeze and I get to appear on the cover of Rolling Stone alongside Silvio Berlusconi.
