To get a more resent xorg distribution than the default in ports, please 
add WITH_NEW_XORG to /etc/make.conf. That should give you support for 
more recent intel graphics cards.  You can also get the experimental 
xorg repo using svn, see http://wiki.freebsd.org/Xorg for details.  The 
experimental xorg repo contains the latest xorg packages that has been 
ported to FreeBSD, and should in general work, but as usual, no guarantees.
