-2.  If nvidia-driver is already installed, the script will abort with
-    a prompt to remove the existing driver (it is not necessary to
-    remove the kernel module).
+2.  The nvidia-installer has been patched so it is now NO LONGER
+    NECESSARY to remove the old driver before running this script.
 
 3.  With Slackware 15.0, nvidia-switch has been dropped once and for
     all as there are no longer any conflicts.
