Well, I tried the mergedfb. I got the most stable mirroring until now (so I get the same picture on both screens), but still can't get both screens to act as one big screen.
However, it seems like I'm *almost* there -- Each screen seems to be double in width, as the width I set in the "Virtual" option of the SubSection Display. If I set "CRT2Position" as "LeftOf" I can only see the left-side of the desktop (I use gnome, and see the left-side of the desktop -- the panel with the menu-icon, the "Start Here" icon etc.) on both screens, and I can see that each screen has another "hidden" screen in its right side. If I set CRT2Position as "RightOf" I see the right-side of the desktop on each screen and there's a hidden screen on the left of each monitor.
Attached is my current XF86Config file (the relative parts, no need to write here my InputDevice's I guess)... any ideas what might fix this?
Thanks alot for your help :-)
