removing nvidia drivers for livna rpms

[Jack Howarth]

     I have in the past installed the NVIDIA-Linux-x86_64-1.0-7667-pkg2.run
package on a dual opteron from Sun. Today after installing the current 
livna rpms for the nvidia drivers I got errors at boot time conflicting
versions of the drivers (specfically between 7667 and 7676 versions).
Do I need to manually deinstall the old 7667 installation and reinstall
the current nvidia drivers for this to work? Thanks in advance for 
any advice.
