I just went to the nVidia web site and it shows the latest FreeBSD
driver supports this GPU "4200M" and the page on Optimus states tha it
is "completely automatic". The driver download page makes no reference
to "Optimus" for any platform. 

It does state that the NVS 4200M is supported on both 32 and 64 bit
FreeBSD with the 270.41.19, the version in the current port.
