 I have an LG X110 that has the same CPU/GPU combo in it. I haven't
 encountered this particular problem with it, curiously.
 
 The first recommendation would be to try a current ("HEAD") kernel, as
 the i915 DRM driver is significantly newer in it than what you'd be
 getting with 8.0 (whether the formal release or 8.0_STABLE). You can
 grab a kernel (and modules.tgz) from the releng builds[1], if you
 don't want to build one yourself. Hopefully you'll get better results
 with it.
