That's about the size of it, pitch trim and rudder become your primary controls.
If that is telling of my ignorance, so be it, but shouldn't an a/c in trouble have elevators? Not a slow, massive Tailplane alone?
Think of this mode as the equivalent of total hydraulic failure on a previous generation jet (like, say, a DC-10). In the previous generation jet you'd have had no control other than thrust, but in this case you have thrust, pitch trim and rudder. I haven't heard of this mode coming into play outside of simulator training (thankfully, like total hydraulic failure it is expected to be an extremely rare occurrence), but it is indeed what you've got.
