From your Xrandr info:

The 1280x1024 bit is the resolution it's using, and the +0+56 is the position the X server has been told to put it - which means the X server thinks its 56 pixels down from the top. That's where your mouse is ending up.

This doesn't appear to be a driver bug. Rather, it's a configuration issue. Try re-aligning the monitors in gnome-display-preferences - the snapping zone isn't very big, so it's quite easy to set up your displays not quite aligned like here.
