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?

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
