mouse in zaphod mode on radeon

After the recent updates of the radeon driver i thouht i'd
try zaphod mode again. I must say i'm very happy that it
works nearly perfect now. There is only one little issue
left. If i use the following configuration of the server layout:

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen          "Screen 1"
        Screen          "Screen 2" RightOf "Screen 1"
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"

Then the second screen is mapped on the right side of the
first screen (how it should). The mouse is initially on
the first screen. I can move my mouse to the right, from
the first screen to the second screen (all fine until now).
But if i try to move the mouse back from the second screen
to the first one, it gets blocked at the edges of the second
screen. i.e. i cannot move it back to the first screen.

Interestingly, if i use anything else then "RightOf" in
the config above (ie "LeftOf", "Above" or "Below") i cannot
move the mouse from the first screen to the second at all.

I thought that it must be some simple check of the cursor
position that is not correctly done and tried to fix it myself,
but got lost in the code and couldnt figure out where the bug
comes from. :-(

I'd appreciate if someone could help me out here.

Why does it take years to find the answers to
the questions one should have asked long ago?
