I have source for a program that is attempting to open /dev/nvidia0 then on failure open /dev/dri/card0 to get some vsync settings.

Neither of those two files is found on my laptop in /dev. Is this because of udev?

No, /dev/nvidia0 exists on my centos 4.2 box in /dev You should check that you have nvidia's drivers installed correctly and that the nvidia module is loaded by checking with lsmod.

Any ideas on what to open to read vsync information from X windows?

I think xdpyinfo gives you this. I can't remember.
