Also, some kms config actually break because we've managed to ship
userspace that uses kms, but in parts also still uses the legacy drmMap
api. Which in our case means we need to have a working (but fake) agp
driver around. This entire thing is one giant mess, but I think with the
gen6+ stuff moved it's about as good as it will get. And I don't mind the
old crap too much, we have an entire dungeon full of them in i915_dma.c,
too ;-)
