That's still correct.

It doesn't, FAM doesn't detect device changes.

It's the other way round. udev notifies HAL of new devices, older HAL
versions call fstab-sync to create fstab entries on demand and
the /etc/fstab change gets noticed by FAM which notifies gnome-vfs. But
gnome-vfs is not responsible for automounting, that's what
gnome-volume-manager does. gnome-volume-manager gets notified directly
by HAL.
