Thank you very much for the notice! It is always nice to receive updates
on the situation of gfx drivers, since some people seem to be asking
about these things ... so I can just ask them to subscribe to this
mailing list ;D

I haven't been using UXA since 10.1, SNA is stable enough nowadays. The
only problem I have with SNA with 10.x is that enabling more than 2
outputs causes X.org to hang. With the updated driver from 3.8 this is
no longer an issue :P
