wait a sec - before the dri2 update, what exactly were you doing? What
happened when you loaded i915kms? Nothing should've been found and no
i915 driver should've been running

There's no haswell support for i915kms, so it shouldn't have worked
/at all/. You should've just gotten either vt(4) or sc(4) + vesa as a
console, and VESA graphics.

As a workaround, you can just not load i915kms, or patch i915kms to
not detect your haswell chipset.
