AGP suspend/resume should already handle restoring of the aperture
and the IOMMU code uses the same.  It has not other state. It might not work 
when the AGP driver is not compiled in/loaded though (I suspect
that is what happened to you) One simple fix would be to just enforce
that in Kconfig when suspend/resume is enabled.
