Ok, that at least confirms my suspicion (and yeah, I've mis-remembered
when I've merged the agp removal for gen6+, it's already all done in
3.6). But I have no idea how that could fail this way. New little
debug patch:

diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c
index a24ffbe..7ec35c5 100644

        return drm_get_pci_dev(pdev, ent, &driver);
 }

Yours, Daniel
