However, it still does only work when at xorg graphics mode, which
already was topic in this thread.
When using it from console, no matter sc or vt, it still hangs with
dark screen and unresponsive keyboard.
Could finishing the suspend/resume work be sponsored, so that it also
works on console-only computers?
