The U160 requires this hack:

diff --git a/drivers/gpu/drm/i915/intel_bios.c b/drivers/gpu/drm/i915/intel_bios
index fb5b4d4..53ff16f 100644
--- a/drivers/gpu/drm/i915/intel_bios.c

                return alternate ? 100 : 96;
        default:

+               return alternate ? 120 : 100;
        }
 }
 
When I work out why, I'm liable to get very angry.
