Description of problem:
Installation of FC6T3 aborts at the early "findrootparts" step if a reiser fs 
partition happens to be found.

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


How reproducible:
Both in VMWare with a virtual disk preformatted (using a knoppix livecd) with 
an extra reiser partition, as well as on my FC5 desktop with a spare partition 
that contains a reiserfs OpenSuSE 10.1 installation. After using "dd" to 
temporarily backup and zero out of the first 1MB of my SuSE partition, 
installation continued as normal.


Steps to Reproduce:
1. mkfs.reiserfs a partition that will be detected by anaconda.
2. perform a default installation

  
Actual results:
Installation aborts. If a graphical install, the screen goes black with the 
mouse cursor stuck in wait state.


Expected results:
Installation to continue as normal.
