The way I have changed video drivers in the past was to use system-config-display to force creation of a new xorg.conf file.  If you 
just want to use the "nv" provided with XORG you won't have to install anything.

To do this, reboot the machine in runlevel 3.  Log in as root, and run system-config-display, forcing a reconfiguration operations:

     system-config-display --reconfig

When the configuration dialog comes up, select the "Hardware" tab and make sure the monitor and video card were detected properly. 
If the video card isn't already set properly, change it to "NVIDIA GeForce FX (generic)" as there does not appear to be a setting 
specifically for the FX 5600.  Click "OK", then run "startx" to test the configuration.  If it comes up OK, you can log out of the X 
session and either reboot or use "telinit 5" to switch to X Window mode.

Hope that helps!
