The patch below is not correct for HEAD or stable/10, because it does
not take TTM/radeon into the consideration.
I did not added the option to compile i915kms into static kernel, because
display console is non-functional in such setup. It is changed in
HEAD and 10 with vt(4) integration, but definitely cannot be made
working on 9.
