For porting the nvidia driver, you most likely can't, because nVidia has a
binary-only part of that module that they would have to recompile in order for
it to work on amd64.
The driver-writing documentation is here:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/driverbasics.html
although I'm not sure how up-to-date this stuff is.
