Yes it works perfectly fine.

I created a bugreport: http://elrepo.org/bugs/view.php?id=839

This part makes me wander though, if I'm correct the second column in
the "lspci -n" output seems to be the class identification. If you
look at the first line of the lcpi output, lspci (or the kernel?)
doesn't seem to recognize the class of some other Intel device, that
probably has nothing to do with the nvidia device at all. It's numeric
class identification seems to be "0000" though (for unclassified?)

Could it be that in the piece of code below (from nvidia-detect), the
device_class is zero because of that line, and nvidia-detect exits?

if (!dev->device_class) {
    fprintf(stderr, "Error getting device_class\n");
    ret = -1;
    goto exit;
