Found a work-around change in drivers/gpu/drm/i915/intel_crtc.c in function
intel_crt_detect
if (IS_I9XX(dev) && !IS_I915G(dev) && !IS_I915GM(dev) && !IS_G33(dev)) {
^^^^^^^^^^^^^^^
which basically forces to use edid reading via ddc and not use
detect_hotplug method which seems not to work. HTH

after first splash boot, screen flickers displaying a bunch of drm: failed to
restore crtc configuration
