At the risk of being accused of bumping my thread here is my PolicyKit.conf.
Note that automount for removable drives functions:

<config version="0.1">
  <match action="org.freedesktop.hal.power-management.shutdown">
    <match usr="jsh">
      <return result="yes"/>
    </match>
  </match>
  <match action="org.freedesktop.hal.power-management.reboot">
    <match user="jsh">
      <return result="yes"/>
    </match>
  </match>
  <match action="org.freedesktop.hal.storage.mount-removable">
    <match user="jsh">
      <return result="yes"/>
    </match>
  </match>
    <match user="root">
        <return result="yes"/>
    </match>
    <define_admin_auth group="wheel"/>
</config>

Any help appreciated
