no worries. I have regrab the reg_dumps (intel-gpu-tools updated and 
re-built) with the same restrictions (xrandr --crtc2 freezes X so I did 
not attempt it):

http://maumae.net/retina/intel_corrupted_drm_debug/ird_i915_loaded_inX_take2
i915 loaded, reg_dump done within X, no-pipeC.

http://maumae.net/retina/intel_corrupted_drm_debug/ird_i915_not_loaded_take2

obtained from the console with i915 not loaded (i915.die=1).

Let me know. Thanks,
Francois
