Shot in the dark here.

NVidia updated their drivers at about the time you started having
problems. Their latest driver update changed the permissions on
/dev/nvidia0  nvidiactl ; resulting in VERY slow scrolling response on
my box (amd64) using googleearth. Changing the permissions to crwxrw-rw-
resulted in instant speed up; you may get by with r--r-- (?).
