Description of problem:
Just tried a rawhide install from the tree containing
rpmdb-fedora-2.91-0.20040907.x86_64.rpm, over NFS.  Graphical install
would not go at all: as soon as X started the screen went black with
no visible cursor and no disk activity.  Had to reset.  Text install
was fine, and X worked after installation without any configuration
changes.

Version-Release number of selected component (if applicable):
anaconda-10.0.2-0.20040901235037.1.x86_64.rpm
xorg-x11-6.7.99.903-5.x86_64.rpm

How reproducible:
100%
