Description of problem:
When attempting to install a new system with a SIS630 integrated video, 
anaconda bombs out. If specifying xdriver=sis during installation the 
installation is successful.

Version-Release number of selected component (if applicable):
FC6 released version.

How reproducible:
Just press enter at the boot: screen of the installer.

Steps to Reproduce:
1. Allow system to start.
2. get mini-wm error
3. reboot
4. Specify 'linux xdriver=sis' at the boot: prompt
5. Install the system successfully via the GUI 
  
Actual results:

Not specifying the driver caused failure. Manually specifying the driver 
allowed successful installation.

Expected results:

Not needing to specifically tell anaconda that I had a particular video 
chipset.

Additional info:

Including lspci -n in attachement for needed information to add to the 
hardware listing.
