This is the latest (for me, JustGreg) official nvidia video driver, 256.33.  It is for the kernel 2.6.33, used by the Puppy 5.0 Lupu distribution only.  One has to use nvidia-xconfig to complete the installation and xwin to start the use of the new driver.  It also includes the nvidia-settings tool to change the driver settings, glxgears to test things and glxinfo. There is also the documentation package in /root. It also has an uninstall script
