Doctor it hurts when I do this..

There is no reason to make a mess of our drivers because people are
doing things they should haver never done and that aren't supported
in Linux.

If Intel didn;t offer any out of tree drivers I'm pretty sure no
customer would even attempt this.  So fix this where the problem is.
