This is the quick&dirty way Dave Airlie suggested to workaround the midlayer drm agp brain-damange. Note that i915_probe is only called when the driver has ksm enabled, so no need to check for that. We also need to move the intel_agp_enabled check at the right place. Note that the only thing this does is enforce the correct module load order (by using a symbol from intel-agp.ko) to ensure that the fake agp driver is ready before the drm core tries to set up the agp stuff. v2: Add a comment to explain why gen3 needs all this legacy fake agp stuff - we've shipped an XvMC library with a kms-enabled ddx that requires it (but only on gen3). v3: Make it clear that this is only a gen3 issue in the comment.
