gnome-mount-0.5 is available: http://www.mail-archive.com/utopia-list@gnome.org/msg00315.html Just for case, Nautilus extension is an official part of gnome-mount now.
the team that does hal says they are waiting until 0.5.9 ( early december ), so we cannot add this until >0.5.8.1 ( required by new gnome-mount ) is in portage.
Reopening to fix resolution.
This was applied to the tree. Thanks for reporting.
