I'm not sure if I got your point yet: AMD64 stands for the well-established x86-64 architecture with AMD-specific parts like the virtualization extensions. All these transistors and specs are broadly available for years. Regarding direct interrupt delivery: on Intel, we do not depend on specific hardware support to provide this feature, and I bet we can port that approach to AMD as well.
