I have the same problem, and the reason (in my case) is not the usefree option, since I don't have. My installation was a Feisty, upgraded to Gutsy and now Hardy. The automount stopped working after upgrading to Hardy.
However, I noticed, that if I disable networking via the nm-applet, automounting starts to work (no need to reboot or log out and in). If I turn networkin on, it fails again. This can be repeated several times.
