via drm in X.org?

[applecom at inbox.ru]

It seems X.org 6.9.0 sources contain drm drivers for FreeBSD kernel among  
other:
X11R6.9.0-src1.tar.gz - xc/extras/drm/bsd-core, including via. But via drm  
isn't included in FreeBSD.
If X.org 6.9.0 really contains via drm for FreeBSD why it's not included  
in FreeBSD?
Correct me If I'm greatly mistaking.
