Description of problem:
Anaconda fails to install a proper driver for PCI-Express ATI RADEON cards which results in a blank screen when trying to start graphical part of installation. This especially happens with X600, X600Pro, X700, X800 and X850 cards. The FC3 distro got the same problem, however FC2 i386 is able to install at least the VESA driver resulting in a successful start of X. 

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. No special steps are needed, just boot-up the installation CD (DVD)
2. Press Enter to choose a standard installation
3. Wait until anaconda starts to detect your video, monitor and mouse
  

Actual Results:  Blank screen as soon as anaconda starts X.

Expected Results:  The X should start so the graphical part of installation can continue
