Since I think you mentioned you'd only be enabling this on newer
chipsets, won't it be a problem for A+A where one A is a generation
behind the other?

I'm not really liking where this is going btw, seems like a ill
thought out concept, if AMD is really going down the road of designing
hw that is currently Linux incompatible, you are going to have to
accept a big part of the burden in bringing this support in to more
than just amd drivers for upcoming generations of gpu.
