Make "load=nvidia" work

Using a squashfs module created from nvidia-kernel and nvidia-driver packages.
A sample script for creating this nvidia module was added to liveslak, see:
./contrib/scripts/makemod_nvidia.
These two packages were created using the scripts from slackbuilds.org:
  https://slackbuilds.org/repository/14.2/system/nvidia-kernel/
  https://slackbuilds.org/repository/14.2/system/nvidia-driver/

Note that the nvidia-driver package was created on a multilib system so that
it could pick up 32bit compat libraries (needed for Steam among others),
and the CURRENT variable was set to 'yes' so that the nvidia drivers are
fully separated from mesa and xorg-server and do not overwrite system libraries:

  # COMPAT32="yes" CURRENT="yes" ./nvidia-driver.SlackBuild
