That addpredict looks like a workaround, not like a real fix of the
problem. Especially, the many warnings mentioned by grozin are still
there. With the patched virtualx.eclass, I still see more than thousand
messages in Xvfb.log:

   libEGL warning: failed to open /dev/dri/card0: Permission denied

Also, was this so urgent that you had to push the eclass change without
prior mailing list review?
