[b]ERROR: Unable to load the kernel module ‘nvidia.ko’.  This happens most
      frequently when this kernel module was built against the wrong or
      improperly configured kernel sources, with a version of gcc that differs
      from the one used to build the target kernel, or if a driver such as
      rivafb/nvidiafb is present and prevents the NVIDIA kernel module from
      obtaining ownership of the NVIDIA graphics device(s).
     
      Please see the log entries ‘Kernel module load error’ and ‘Kernel
      messages’ at the end of the file ‘/var/log/nvidia-installer.log’ for
      more information.[/b]
