The module init code is somewhat misplaced in i915_pci.c, since it needs to pull in init/exit functions from every part of the driver and pollutes the include list a lot. Extract an i915_module.c file which pulls all the bits together, and allows us to massively trim the include list of i915_pci.c. The downside is that have to drop the error path check Jason added to catch when we set up the pci driver too early. I think that risk is acceptable for this pretty nice include.
