Excerpt from X.org history:
X11R6.7.0, the first version of the X.Org Server, was forked from XFree86 4.4 RC2.
So we really have x.org. Actually it is possible to extract the version number for the xorg release from the Announce files. WildWizard already brought the updated table segment. For some reason I cannot edit the original post anymore...
