Hm this is somewhat surprising, at least with atomic, since DPMS as a separate thing doesn't exist anymore - it's the same path as any other modeset. With the suspend/resume helpers even the same as after resume. But of course in reality there's always potential for some differences between boot-up state and what your atomic_disable leaves behind to creep in. Just figured I drop this in quickly, always great to have more hw drivers showing up!
