Abilities to disable the IOMMU as a choice? Performance impact on 
various systems and interactions with other projects that have gone to 
some length to work within S/G and its performance characteristics. How 
will this affect them? Cache effects? Interactions with some VM work 
currently being undertaken?

I can't imagine such a major change being closed/approved/automatic.
