I\'m sure I saw before somewhere, specifying a value for xml ifconfig statements (as default is just boolean). Anyways, disabling modules in the admin doesn\'t actually work
You could create a separate enable setting using nothing but your module's system.xml.
system.xml
YOUR MODULE select adminhtml/system_config_source_enabledisable 1 1 1
Then use the new setting in the layout file:
mytemplate.phtml
