Well if every vendor ends up implementing something different for this
purpose and it can be solved with just a few lines of common kernel
code, IMHO it might just be worth it.

Depends on the initrd and the hardware, of course. Certainly you can
implement the same on initd, but you can never make it as fast as this
one. Moreover, this solution would have a common 'user interface' for
the functionality if anyone cares about the userspace unification
