Yes, the Xfree86 log file is where I find the "(EE) NVIDIA(0): Failed to initialize the NVdriver kernel module!" message.
There is also a message saying "Screen(s) found, but none have a usable configuration", but I believe that always shows up if the nVidia driver fails. I could of course be wrong. If it's an essential message, I apologize for not including it in my first post
