drm/i915: VGA needs to be on pipe A on i830M The bit doesn't stick, and the output is always cloned from pipe A, even when it's supposed to scan out from pipe B. Shuts up annoying warnings from the modeset-rework, too. I've noticed that with this patch we know get and unknown connection state since the code can't find a suitable pipe for load detection. But that beats the previous state of affairs, where it tried to use pipe B, actually used pipe A and concluded that something is connected (although it's the LVDS on pipe A and nothing on the VGA connector on pipe B). I've tried to make load detect work by remapping the pipe->planes stuff, so that crtc 0 will use pipe B and hence we still have something left for load-detect on pipe A. But alas, that upset the hw a bit. So there's still some things to figure out, but this here will at least paper over some of the problems.
