Hi Christian,

This change appears to have semi-broken vdpau on nouveau. Whenever I
flip on the OSD in mplayer, the rendering becomes *extremely* slow.
However regular up-scaling without the OSD is plenty fast. This
effectively is forcing the output surfaces to live in GART instead of
VRAM. I believe that the OSD involves blending of some sort, so I can
definitely imagine that being slow. Any thoughts on the proper way to
address that? Removing the PIPE_BIND_SHARED from that line "fixes" it.
