Description of problem:
When installing Mageia1, test option for the graphic nouveau driver crash with my graphic card 8600GT.

Version-Release number of selected component (if applicable):
- Mageia 1 Alpha 1
- Twintech GeForce G8600 GT - 256MB DDR3 - HDMI
 http://www.twintech3d.com/products_features.asp?num=175
- x11-driver-video-nouveau-0.0.16-0.20110107.1.mga1.i586.rpm

How reproducible:
When installing Mageia1, I choose to replace the default x11-driver-video-nv driver by x11-driver-video-nouveau to have 2D accelerated and I choose to test this configuration by clicking on the Test button before finishing the X configuration but I have an error.
