Description of problem: Anaconda, before formatting the hard disk,
before installing packages, decides its necessary to add rainbow
colors to the screen. 

Version-Release number of selected component (if applicable):
/export/fedorappc/Fedora/RPMS/anaconda-10.0.2-3.ppc.rpm
(rawhide 9/11)

How reproducible:
100% (okay, I lied, I tried this twice)

Steps to Reproduce:
1. Start installation on Mac with Radeon 7500
2. Nice graphical boot (happy!)
3. Suddenly screen becomes rainbow colored when we reach the
partitioning stage
  
Actual results:
Rainbow colored screen

Expected results:
Nice normal colored screen

Additional info:
Which you get back by going to a console and back to the graphical
installer. Its a low priority, if we don't fix it, we'll just clog the
release notes about it as a quick workaround
