Not sure that it did :) I tried it once early on, and it concerned me enough I never tried again. It was clearly in a violently erroneous state! At one point, X *could* resume the display. This makes me think the problem is solved via the graphics "chip" state, but it could be an acpi thing. I can't remember if I ever tried to startx after the resume on the "blind" console.
