I have the same card as you and mandrake 8.2 so this may not be the case in your system.
BUT, I had to manually edit two other files.
I added the line
nvidia to /etc/modules
and added the line
alias char-major-195 nvidia to /etc/modules.conf
Also comment out any line that has NVdriver in it.
I don't use startx either. I just switch to init 5 and let the system start the xserver.
