To use these drivers, make sure that you have loaded the NVidia kernel
module, by doing

	# kldload nvidia

or adding

	nvidia_load="YES"

to your /boot/loader.conf.

If you build this port with FreeBSD AGP GART driver, make sure you have
agp.ko kernel module installed and loaded, since nvidia.ko will depend
on it, or have your kernel compiled with "device agp".  Otherwise, the
NVidia kernel module will not load.  Also, please set correct value for
``Option "NvAGP"'' in ``Device'' section of your X11 configuration file.

When building with Linux compatibility support, make sure that linux.ko
module is available as well (or have it compiled in kernel).  It can be
loaded via /boot/loader.conf, or later in the boot process if you add

	linux_enable="YES"

to your /etc/rc.conf.

If X.org cannot start and reports

	(EE) NVIDIA(0): Failed to obtain a shared memory identifier.

in /var/log/Xorg.0.log while actually you have ``options SYSVSHM''
enabled in kernel, the sysctl ``kern.ipc.shmall'' should be increased.

See /usr/local/share/doc/NVIDIA_GLX-1.0/README for more information.
