nVidia driver reinstall

I have two systems both running Debian with the 2.4.x kernel. On both machines when I install the newest Nvidia install 7667, they both work, but as soon as I reboot, neither one of them works until I reinstall. What can I do so I don't have to reinstall the driver every reboot?

"neither one of them works" means what?

Sorry, should have been more specific. I guess the problem is I installed NVIDIA's driver, then when I grabbed one of the nvidia development libraries, it grabbed the Debian NVIDIA driver, and installed over NVIDIA's driver. Now I guess there are some scripts in init.d that get run by the Debian driver that screw up NVIDIA's stuff on boot. It always gives me fatal errors when I try starting X like right now I got it down to "API mismatch, because the X module is .7667 and the debian driver is like .71 something".

Well, look in init scripts and see what exactly does what?

Or just uninstall everything - go back to svga drivers - and then start over.
