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. ;)
