Thanks Keith. I think I see what the problem is now. Your memory map
shows that there are some regions that need runtime mappings that
weren't being setup with the original patch because they're not of type
EFI_RUNTIME_SERVICES_DATA. What the patch should do is check for the
EFI_MEMORY_RUNTIME attribute.

Can you try this patch and see if your MacBook Air still boots?
