Would it be possible to have this added to the /etc/init.d/pbbuttonsd
script within the force-reload option? Looks like if the old
/var/run/pbbuttonsd.pid file is there the pid of the message que should
be easy to get. My quick and dirty 5 second hack was:
ipcrm msg `ipcs -q -p |grep -f /var/run/pbbuttonsd.pid |awk '{ print
$1}'`
This would make it automagic to less google savvy users for the future.

pbbuttonsd became unstable after upgrading the unstable debian package
and then trying to blank screen "sleep" the computer by pressing the
power button on AC. It never made it to launching all of the
appropriate scripts.
I had to reboot my ibook g3 900 dual usb (kernel 2.4.24) after I
upgraded, but after that it works perfectly. I like the new event.d and
scripts.d features.
