Why did you expect it to break? do you need an older nvidia driver that
is not supported in xorg 1.14+

That package would be from the old package system. It would mean
removing the newer pkg to install it. Though you should be able to untar
it into place, after removing the existing xorg, which would also
uninstall dependant ports...

The problem with xorg, is knowing what versions work together, by
installing an older xorg you may break the newer input-mouse or libGL...

The only reliable way I would expect to work constantly would be to use
an old ports tree with the versions you want, each port in the tree
would also match up with the same version.

Looking through the svn logs, revision 374489 updated xorg to 1.12.4
which includes security fixes that aren't being back ported to 1.7.7 so
xorg 1.7 gets marked as forbidden. (WITH_NEW_XORG is needed to build
1.12 otherwise 1.7.7 is bult) The next commit removed 1.7 completely

If you do want to go back to 1.7.7 then you could checkout an svn
revision of 374489 or less than 374982 and use that ports tree to build
your own ports.
