My suggestion is to try it with an actionListener. I think you'll find that the model is populated with the current value of the list box by the time it executes, but you'll know for sure if you try it :)
I converted a facelets page to ajax using only <a4j:support> and <a4j:region>, and it seemed to work well enough. I would not expect any difference for JSP. The only issue I did hit was that reRendering a different part of the page after doing a resetValue() on components in the different part of the failed to fetch the model value for the component -- it continued to use the submitted value at the time of the ajax submit.
