Important. These are proprietary drivers. That means the code in the driver software is proprietary to nVidia. OpenMandriva developers can not touch, modify, or even read this code due to legal restrictions which nVidia company takes very seriously. We can only package their code so it installs on OM Lx system. The code itself we can not fix even if we want to.
Many folks in the OM contributor group believe that nVida does not play fair with Linux distros making things especially difficult for small groups like OpenMandriva. More from the inventor of Linux here.
More on what led up to the announcement here of this software avaliability for OM Lx 4.1 users here and here.
