I need the new module since nVidia claims having put a lot of logic there. Without
loading it, the screen remains black, block cursor available, no graphics, but switching
console remains functional. Loading nvidia.ko only leads to that behaviour,
nvidia-modeset.ko reels in nvidia.ko and everything is fine again. As I refered to
PR  201340.

CURRENT clainms to have a new 64bit capable Linuxulator, but it should reveal itself as
linux64.ko - as I extracted from several posts. I persoanly do not need Linux ontop of
FreeBSD, neither 32bit nor 64bit, I have my Linux servers and desktops were FreeBSD isn't
capable or to clumsy (mostly moderate or modern graphical devices and scientific GPGPU
issues). So, I'd like to get rid of the linuxulator kernel module.
