Our developers have the Maya 2009 jobtype in their short-term development plan and are looking into it. We do not have an exact ETA, though it is coming.
As an alternative, you can use the Maya BatchRender SimpleCmd jobtype with Maya 2009 now, as it leverages the "Render" commandline executable and does not need additional plugins. There is also an in-application submission that can be installed from the QubeGUI under the "File->Install App UI" that will place an item under the "Render" menu in Maya.
