We want future generations to at least attempt to use all features, so restrict the stolen memory disabling when vt-d is enabled to the latest generation we have reports for. Which is a HSW per the original report. Also once we get a bit a hold of some of the mysterious framebuffer in stolen memory issues that still haunt bugzilla, we should probably drop this hack again and see what happens.
