Yesterday me and aleph completed the pciaccess rework for
the amd_drv.

But as we rebased on the latest xserver git head, we
stumbled into the dev-privates rework.  We currently
have an unfinished, untested patch which will be
hopefully complete by this weekend.

Both patches are intended to keep backwards compatibility
with older xservers.  It would be nice if someone could test
it on Xorg 1.4 and let me know.
