Managed to get the GUI up and running again, but still no luck with drivers.
Here's the output of "lspci | grep VGA"
00:0d.0 VGA compatible controller: nVidia Corporation GeForce 6150SE nForce 430 (rev a2)
My system is up-to-date and I'm currently using kernel version 22.214.171.124-174.2.3.fc12.i686. Don't know where to go from here.
