I just found that after making the edits to the config.xml file I mentioned in my initial message, after starting Geronimo again and opening the config.xml file again, the 'load="true"' attribute goes away from the axis2-deployer module, changing from the following...
<module name="org.apache.geronimo.configs/axis2-deployer/2.2.1/car" load="true"/> ...to the following... <module name="org.apache.geronimo.configs/axis2-deployer/2.2.1/car"/> -- Sent from: http://apache-geronimo.328035.n3.nabble.com/Users-f328036.html
