The freebsd port nvidia-driver provides a better driver
support that XFree86 to many nvidia card.
It supports also TWINVIEW:

<from README>
TwinView is a mode of operation where two display devices (digital
flat panels, CRTs, and TVs) can display the contents of a single X screen
in any arbitrary configuration.  This method of multiple monitor use
has several distinct advantages over other techniques (such as Xinerama):

  o A single X screen is used.  The NVIDIA driver conceals all
    information about multiple display devices from the X server; as
    far as X is concerned, there is only one screen.

  o Both display devices share one frame buffer.  Thus, all the
    the functionality present on a single display (e.g. accelerated
    OpenGL) is available on TwinView.

  o No additional overhead is needed to emulate having a single
