Thanks to all who helped testing!

The X-Server has been patched to the latest 1.7.X series, drivers
and fonts have been updated to the latest versions. This update includes
some components from Xorg 7.6 with a lot of improvements, and it seems
that the performance is much better than the old version. Also this
Update fix build issues with clang and binutils 2.17.50 in current,
remove 6.X gruft and de-author pkg-descr.
