I am not sure I understand your reply. The offered patch set does not rip out 
existing code. It adds a replacement implementation which can be enabled 
during compile time. Yet it is even disabled per default (and thus the legacy 
code is compiled).

I see such a development approach in numerous different kernel core areas: 
memory allocators (SLAB, SLOB, SLUB), process schedulers, IRQ schedulers.

What is so different for the realm of RNGs?

Ciao
Stephan
