Correct. Only late in the discussion Warner mentioned that the kms drm drivers need to be loaded. So my request has became moot. The drm kmod drivers usually are being associated as graphics drivers for xorg. Thus it is not at all intuitive/obvious that these are also required on console-only computers to make resuming succeed. Given this, it is rather a *documentation* *issue*, as the necessity to install/load the drm kmod drivers is *not* mentioned anywhere in the documentation regarding suspend/resume, making users wonder why resuming fails.
