Indeed it does change something, but the result is even worse :(

1. Now, I can only work on screen 1. I can move a window to screen 2, but
after I want to maximize it, it maximizes to screen 1. When I want to move
a window on screen 2, I can't - it goes back to screen 1 once I want to
move it.
Not to say screen 3 is now totally unusable (accessible only by a mouse

2. My first screen is rotated (by 90 degrees). With Xinerama enabled,
panel menu is shown somewhere in the middle of a screen, and there is no
way to move it to the bottom.

That's all with KDE 3.5.6.
