I don't think this is feasible. v4 is mainly targetted for embedded systems 
with everything available in hardware, with only a few things emulated in 
software to make different hardware look the same. 

Even the TTPCI cards don't fit to v4 at various places, not to speak of 
budget cards around. 

IMO it's not worth the effort.

I'm sorry, I cannot comment on your ideas. I have written only very basic 
userspace applications for v3 and never touched the v3 core, because I 
already worked on v4 very early.

Michael.
