The audio driver uses the power well provided by our driver, so on Haswell we can't "rmmod i915" if we don't "rmmod snd_hda_intel" first. The problem with removing snd_hda_intel is that we also need to kill its users. On the specific machine I tested, the only user seem to be alsactl, but on other machines this may change. IMHO we should leave the "kill user space" step to whoever is running the script, but Daniel asked me to put it here so we have a better chance of Just Working on QA's machines.
