When I was working on big desktop mode with my Radeon 7000 (and the
free driver), I had the feeling that this is the way big desktop is
supposed to work. Because the big desktop is 2560x1024, your mouse can
be in any place of this desktop. There is some hinting support for
"avoiding" the invisible areas, but it did not work very well (at
all?) for me. My advice is certainly to match the vertical resolution
of both screens.

The other option I have found is to move the view point with the
mouse. At least for the free driver this works for both screens (even
with different resolutions). It sounds very clever, although I could
imagine that it can also be annoying in certain cases.
