It is only when you use different scaling to make the same size print from each system the shake becomes more apparent.
I keep coming back to this, both here and the thread on BF, but I just can't get my head round it... in your example blur caused by camera shake is more visable in prints from a crop camera (have I got that right)? That means that there is some camera shake.

What I am saying is that if I can shot at a given speed on a full frame camera and completely eliminate camera shake then surely this shame shutter speed would be fast enough to do the same on a crop camera.
For example, say I can shoot at 1/400th at 400mm on a full frame camera and completely eliminate camera shake then the sensor would not have moved. So the system of scaling the movement becomes irrelevant and the same shutter speed would be needed for a shake free image on a crop camera.
