Nvidia
From FreeBSDwiki
nvidia is the FreeBSD port of the nvidia graphics driver. It is found in /usr/ports/x11/nvidia-driver.
To activate the nvidia driver in X after installing this port, change the nv (or vesa, etc.) in the Device section to nvidia. You can also run X -configure to let xorg figure it out. You might want to add the DefaultDepth directive to the screen section, otherwise you will have only 256 colors.
