As of the jQuery 1.5, there is a local beforeSend callback that can be bound to your request. Documentation link and another documentation link

EDIT: The request data is available in the jqXHR object, the first parameter beforeSend callback.

beforeSend(jqXHR, settings)

Try inspecting the jqXHR object in firebug to see exactly where it stores the POST data and just append your values,
