This mail was accidentially sent a little bit too early ;-)

What I wanted to add is just that with letting it up to userspace, it
would also work in all cases, with or without lock, it would just give
userspace more possibilities and might be more convenient for those
systems where the dock station locks the machine. But I clearly see the
advantage of not needing a userspace helper and for getting this docking
thing to work in 99% of all cases ;-)
