ghm... chmod really helped (most of the time I am real idiot:) - but I
am not sure how to combine it with hotplug... AFAIK udev can easily be
tuned to fix /udev/* permissions - but this is /proc filesystem, so
this is a bit tricky. Also, the biggest question is still about
security - could this be recommended for real life useage - allowing
ordinary user write into this file? It would not be wise to create a
code based on security breaches...
