Thanks Tiago. I know that we are running an older server; it is
currently the one that is released by debian. This is an embedded
device, this is certainly its last upgrade, and until debian drops a
release with a new version of the server, I am going to stay on the
I know that a libpciaccess port has been written for this source, and
I thought about backporting, but I do not want to get into the
situation where I am building the xserver if I can help it. I greatly
prefer using a distribution like debian for most items, then only
change what I have to. Our next project will probably move to ubuntu
which seems to be kept updated with X more often than debian.
