By putting "auto" on removable drives would return an error during startup if media is not present, so not a good idea IMHO. Actually, it should just work as in Hoary.
Are you using KDE? If yes try looking in the Ubuntu forum, this removable media issue has been reported quite often especially in Kubuntu. The autodetect and automount in KDE seems to be broken. Ubuntu which uses GNOME seems to be less problematic at this point of time.
