Bug#388811: xlibmesa-dri: upgrade to xorg 7.1 causes savage opengl stop working

[Thibault Mondary <thibmailbox-deux@yahoo.fr>]

Package: xlibmesa-dri
Version: 1:7.1.0-1
Severity: critical
Justification: breaks unrelated software

An upgrade from xorg 7.0 to xorg 7.1 causes 3d stop working with savage
dri driver (with a mobile Prosavage KN133 "twister").

glxinfo report "direct rendering=yes" but glxgears and any other opengl
app are just displaying black screen, without crashing the whole system.

I think this bug is the same as described in https://bugs.freedesktop.org/show_bug.cgi?id=6357
