    Wow, that's a pretty impressive light-show ;-) Are the wrong colors
    always wrong in this manner, or does it change from boot to boot?


everything (color and sync) are always wrong in the same manner.

the last git version of intel_reg_dumper gives me:
with i915 loaded:
http://maumae.net/retina/intel_corrupted_drm_debug/ird_i915_loaded
with i915.die=1:
http://maumae.net/retina/intel_corrupted_drm_debug/ird_i915_not_loaded

hope that helps, Thanks,
Francois


    Another thing is to try is to prevent the i915 driver from loading
    (e.g. with i915.die=1) and peek at the register settings the efi
    framebuffer driver uses (I presume those work). Please grab the latest
    intel-gpu-tools git from

    http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/

    and attach the output of intel_reg_dumper both when using efifb and
    when using i915.ko.

    Thanks, Daniel
