I have installed the nvidia drivers on mandrake 9.1 twice and edited my xf86config-4 file and both times it crashed X and I had to reinstall mandrake because i am a newbie. I have a gforce4 440 . It keeps telling me that the " module is tainted" and please go to http://www.tux.org/lkml/#
export -tainted . my kernal is an updated mandrake kernel with the source kernel as installed kernel 2.4.
