The issue is not whether it is a loadable module or a driver.  Nobody
here is stupid enough to say, "hey, now it's a driver/module, all of the
complex VM interactions are finally fixed!"

If folks don't want this in their system, there's a way to turn it off,
today, with the sysfs tunables.  We don't need _another_ way to turn it
off at runtime (unloading the module/driver).
