NVIDIA driver *taints* kernel???

[Steven Pasternak]

I use fedora 3 on an athlon xp and an nvidia geforce fx 5200. I go to install 
the Nvidia driver version 1.0-6629 and during the installation at the end it 
says that the license 'Nvidia' taints the kernel, but it still continues and 
seems to work. If I boot in runlevel 5, though, it gets to the part where it 
starts X (right at the beginning) and X doesn't start - It freezes. I 
uninstall the driver and use the 'nv' driver and it works. I have to compile 
the kernel module because it can't find one at the nvidia site. When I'm in 
runlevel 3 I can run the accelerated graphics until I shut down, then I have 
to boot runlevel 3 and recompile the module again. Any advise?
