buenas, acabo de bajarme de www.kernel.org esta version del kernel y he
probado a instalar los drivers oficiales de nvidia pero en la instalacion
me da un error, este es el .log que me deja:

WARNING: Your kernel was configured to include rivafb support as
         a loadable kernel module.

         The rivafb driver conflicts with the NVIDIA driver; the
         NVIDIA kernel module will still be built and installed,
         but be aware that the NVIDIA driver will not be able to
         function properly if the rivafb module is loaded!

ERROR: Unable to load the kernel module 'nvidia.ko'.  This is most likely
       because the kernel module was built using the wrong kernel source
files.
       Please make sure you have installed the kernel source files for your
       kernel; on Red Hat Linux systems, for example, be sure you have the
       'kernel-source' rpm installed.  If you know the correct kernel source
       files are installed, you may specify the kernel source path with
the
       '--kernel-source-path' commandline option.

ERROR: Installation has failed.  Please see the file
       '/var/log/nvidia-installer.log' for details.  You may find suggestions
       on fixing installation problems in the README available on the Linux
       driver download page at www.nvidia.com.
