I have no idea what happens on your "clean boot system" configuration. Does the
desktop environment run? Do you have X running?

That "i915.ko still loaded!" message really suggests there are programs you
need to kill before doing the tests. Please make sure your testing environment
is correct before you try to run module_reload.
