I use the free radeon driver, and in the man page, it says:

              For example, if you wanted a desktop composed of two
1024x768 viewports
              looking  into  a  single  desktop you would create a
virtual desktop of
              2048x768 (left/right) or 1024x1536 (above/below), e.g.,
              Virtual 2048 768 or Virtual 1024 1536
              The virtual desktop can be larger than larger  than  the
 size  of  the
              viewports  looking  into  it.   In  this case the linked
viewports will
              scroll around in the virtual desktop.  Viewports with 
different  sizes
              are  also  supported  (e.g.,  one  that  is  1024x768 
and  one that is
              640x480).  In this case the smaller viewport will 
scroll  relative  to
              the  larger  one such that none of the virtual desktop
is inaccessable.
              If you do not define a virtual desktop the driver will
create one based
              on the orientation of the heads and size of the largest
defined mode in
              the display section that is supported on each head.

So I think this means that you can just specify the size of the
virtual desktop, and then the smaller screen can be moved up and down
following the mouse, so that you can see every corner of the virtual
desktop. I think I had this working, but I found it a bit disturbing.

I am not a big fan of the binary only driver, so I am not sure whether
this works here, too. But it would be worth a try.
