Are you sure you have linux-image-extra installed on the Kabylake system ? I installed on a non-i915 system and was able to modprobe the i915_bpo module without encountering any missing symbols. I am going to hold off on this pull request until you are a little more sure of your bits. rtg

Yeah, I figured it out.. the KBL system had linux-signed-image of the same abi version installed and that conflicted with the local kernel image build, so I purged linux-signed-* and it works fine now. so I think it's fine to merge now :)
