I have a WD 250gb My Book about two years old and has never had a problem with it mounting/unmounting automagically. I use Gnome also.
gnome-volume-manager isn't installed by default so I installed it, it doesn't seem to give me the option to run the commands I need after mounting/unmounting.
The My Book is a different creature than the passport, so it doesn't surprise me that you don't have the same issues.
In my fiddling I have managed to write a udev profile which creates a /dev/passport node, but I can't eject it from nautilus and it also doesn't seem to execute the commands I need, and I can't figure out when the 'action remove' part is being called, if at all (is this called on umount or only after I have physically pulled the usb plug from the computer?).
