[drm:i915_init] *ERROR* drm/i915 can't work without intel_agp module!

doesn't look good,

though I still haven't had a successful intel/nvidia switch as I lack
the hardware, and nobody has worked out exactly which ACPI method is
used to switch the MUX.

if you can get a dmesg with i915 and nouveau loaded then open a bug on
bugs.kernel.org I can try and work with you to figure that out,

Dave.
