[arch-general] nvidia and xorg-server 1.9

I was following the discussion about holding back xorg 1.9 because of the nvidia driver, but I either missed the end of it, or it was left open. Do the nvidia and nvidia-173xx drivers in [extra] work with 1.9? If they do work, either or both, are they still plagued by this performance regression (stuff like rendering fonts as far as I can remember). If either does have this performance hit, does anyone know of a target version that resolves the regression? Thanks
