Thanks again Estel, I recognized this behavior of debians xbindkeys before, but my workarround was to "killall xbindkeys" regulary as I never have easy-debian up all the time.
I am testing your solution let's see if there are major drawbacks in the battery lifetime with the maemo xbindkeys permanently on...

EDIT: one useful addition: to use Rehanna's middle- and rightklick-Hack one have to install/copy xdotool in maemo too! Now it is perfect!

Have a nice weekend!
