Henri Cook:
I had the same "jumpy" issue when upgrading to Jaunty.
Fixed it using a solution from further up in comments-- adding Option "AccelMethod" "xaa" to my xorg.conf
I'm not sure what "xaa" does (I'll do some reading later today, 'cause I'm curious now) but it significantly improved my user experience (i945/GM).
