There is the window.scrollbars.visible attribute which should be false
and true according to the specs, but firefox always tells me it is
true and MSIE does not allow it on non-popups at all.

You could read the height of the browser and compare it with the
height of the main elements and display the backto link when the
latter is bigger than the former.

However, this is a lot of work for some functionality users are not
likely to recognise or need anyways.
