I put in a Geforce 256 DDR card into my system (had a Voodoo 3000
before). After the install Xconfigurator crashes at 2cd screen
with a core dump. I tried to reinstall the OS and get it working
that way. It works (although it did not automaticall detect at
Geforce 256 DDR it only detected at Deforce 256. It works now
for X, but Xconfigurator crashes everytime I try to run it.
(with and without the --preferxf4)
This should be fixed with the Xconfigurator currently in rawhide.
