What's the xf86-video-intel version? 2.9.0 is required.
This new processor is only supported in kernel mode setting. Can you try enabling CONFIG_DRM_I915_KMS or boot option i915.modeset=1? That will report VGA1 instead of VGA in the log (as shown above).

If that still doesn't work, please file a bug referring to http://www.intellinuxgraphics.org/how_to_report_bug.html. We are definitely interested in report against this new processor.

Thanks
