Right, the modern drivers are dependent upon having KMS and GEM in the
kernel. In comparison, supporting a gen1 backend in the DDX is trivial.

There's no incentive in Intel for supporting 81x, but both Daniel and
myself have muttered that we should jfdi. As I have no 81x hw, you are
welcome to do the KMS port...

To reiterate, you need to downgrade Xorg (xorg-xserver) to restore XAA
support for your chipset.
