I've been running with this patch[1] for a few days now without problems. The images are smoothly scaled.

I modified the patch to insist on Cairo 1.9.2 since ubuntu 9.04 ships with the cairo fix backported. I also had to change the X server version check because my X server didn't pass, but I've seen no artifacts in the images, so I assume the properietary nvidia driver correctly implements the needed functionality.
