Unfortunately, upstream has vanished by the end of last year. I have reviewed the source code together with Hans de Goede of Fedora fame and he has already uploaded his RPM package, which includes our common patch set, to RPMFusion. We agreed to keep sharing patches among each other and even decided to take over upstream maintenance on github some day.
This should not be necessary anymore, as the upstream project page is back to life since Feb 11th: <http://www.chaos-software.de.vu/>
