Which is the root-cause preventing i915.ko from loading. Now with 3.7 we /shouldn't/ all that agp crap any longer on snb/ivb, so I'm a bit confused why it still tries to initialize it. Can you maybe attach your .config? Also, we need to employ some dirty runtime tricks to no longer require agp on newer chips, since we still need to keep it around for backwards-compat with old userspace on old chips. Can you please check with the below diff whether this hack works?
