Dear freebsd-current mailing list,
I created a patch to support kernel mode setting on Intel Haswell. The
patch starts below:

This patch is untested, despite the fact that I'm typing this from a
computer with Intel Haswell, I have a nVidia card in my computer. On the
other hand, this patch does compile without errors.
Thanks,
