I recently installed nvidia's drivers for my GF4 (which is now dead, unfortunately) under Mandrake 9.1, and found it to be quite easy for a newbie such as myself, thanks to good documentation.
First off, I never found out how to quit the X-server without shutting down totally or rebooting, so instead I used Mandrake Control Center -> Hardware -> XFdrake -> Options to set it to *not* boot straight into X.
After that, a reboot, and I got to the console and SU'ed.
Navigated to the folder I downloaded the archive to and typed:
sh WhatEverTheArchiveNameIs.run (remember it's case-sensitive)
The installer did it's thing, I can't remember if there was any interaction there or if it just did everything itself, the latter, I think.
Reboot to the prompt, type 'startx' (without quotes) and boot into X.
Then I edited my XF86Config-4 as described in the drivers readme in section 3, i changed one word and added one line, IIRC, quite easy, it's all in the readme. XF86config-4 is in /etc/X11
Then I ran XFdrake again and set it back to boot straight into the GUI and rebooted .... all done
Well almost, I had to fiddle a bit more with XF86config-4 to get Twinview and TV-out set up, but it's all in the readme.
