Ahh, yes - XFree86.0.log. Sorry, forgot to say. I hesitate to post the entire XF86Config-4 and the log - too long. Perhaps the following from /var/log/XFree86.0.log will suffice. These are the only errors reported:
II Loading /usr/X11R6/lib/modules/drivers/nvidia_drv.o
No symbols found in this module
EE Failed to load /usr/X11R6/lib/modules/drivers/nvidia_drv.o
EE Unload module "nvidia"
EE Failed to load module "nvidia" (load failed, 0)
lsmod does show the NVdriver.
