The difference is that debians gnome-volume-manager calls pmount, which runs in
your session and checks the groups of the caller. As soon als
gnome-volume-manager in debian shifts to the hal callouts it will fail too.

I'll add a note in hal's README. I don't know if the KDE part that does the
mounting has some info about the plugdev group, but it would be nice to add
some info about this there too.
