Ah, of course! My bad... They are different buses and connectors. I
was really thinking more of the 'gart' part of the agpgart.

Is there any requirement/need/value for something like a PCI-E-gart?
Or does this relocation requirement go out the window somehow when a
graphics device moves to PCI-Express?
