Installing Ubuntu's supported ATI driver fixes the problem.

Can verify that with the supported ATI driver installed,

       xserver-xorg-d 6.5.7.3-0ubunt X.Org X server -- ATI display driver,

that matrixview and other rss-glx screensavers run much faster, not 
quite as fast as fglrx with xscreensaver, but perfectly acceptable.
