I'm trying to show that if you let HAL - which runs as root - mount the
decvice, it will be mounted as root.

Its odd, but I can mount my USB devices as 'anton'.
Its back to the MAN pages.
In this case the MOUNT man page, which explains how non-root users can
mount things:

       The non-superuser mounts.
              Normally, only the superuser can mount file  systems.
              However, when fstab contains the user option on a line,
              anybody can mount the corresponding system.

A little later it goes on to say

        For  more  details,  see fstab(5).

Which gets back to my point about reading other man pages well :-)

Further, it says

        The owner option is similar to the user option, with the
        restriction that the user must be the owner of the special
        file. ...   The group option is similar, with the restriction
        that the user must be member of the group of the special file.

I expect you'll find /dev/sdb1 is root.floppy.  If it was marc.users
there would be no problem.

Well, part of the "it works for me" was to alter the entry in /etc/fstab
in accordance with the man page.
