Description of problem:
When enabling Compiz with KMS on Intel Corporation 82945G/GZ Integrated Graphics Controller [8086:2776] (rev 02), the screen is unusable due to flickering for every mouse move.

Version-Release number of selected component (if applicable):
xorg-x11-drv-intel-2.8.0-13.20090909.fc12.x86_64
kernel-2.6.31-2.fc12.x86_64
compiz-0.8.2-14.fc12.x86_64

How reproducible:
always

Steps to Reproduce:
1. Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration
2. Ensure the file /etc/X11/xorg.conf does not exist, or is a known-good configuration file that uses the 'intel' driver
3. Shut your system down entirely, then start it up again
4. Enable Compiz: menu -> System -> Preferences -> Desktop Effects, click Enable Desktop Effects
  
Actual results:
flickering and unusable screen

Expected results:
Working fine.
