Just because I'm curious, I wonder how this research does or shoud look like.
Defered probes did come to light with 3.4, that was more than 2 years ago. Ok, most people (like me) just noticed it during the last months when they switched to DT and have run into a problem (the deferred probe mechanism is an error-message killer), but some must have seen it already 2 years ago.
And I wonder how the ACPI world solves that problem. My guess would be hardcoded stuff in the firmware-blob (BIOS), just like it happened with board files, but I've never seen BIOS code and my knowledge about ACPI is almost zero. ;)
