First of all, I have uninstalled dbus-python to be able to confirm that there
are better error messages now:

Thanks!
However, the current hal support does not do better than the old code;
to the contrary, hal's error message is even missing a "not": ;-)

DBusException: org.freedesktop.Hal.Device.Volume.PermissionDenied:
Device /dev/hdc is listed
in /etc/fstab. Refusing to mount.
Nevertheless, KDE is able to perform the mount (presumably via HAL) properly,
so my idea was to look at their code:
http://websvn.kde.org/branches/KDE/3.5/kdebase/kioslave/media/mediamanager/halbackend.cpp?revision=864963&view=markup
However, they're using libhal, so the interaction via DBUS is a little hidden
AFAICS. OTOH, the isInFstab function uses the suspicious flag
KMountPoint::NeedRealDeviceName of KMountPoint, which would be here:
http://websvn.kde.org/branches/KDE/3.5/kdelibs/kdecore/kmountpoint.cpp?view=markup
So obviously, KDE scans fstab (via fstab.h's API if available) and explicitly
resolves symlinks.
But it also has fallback code for devices that are not in fstab, so that may
be completely unimportant.
