Indeed, you are doing the right thing, I guess. But if you encounter any 
sort of crash, I really advise you to go against gentoo on this and 
update your kernel to the latest official release (3.12.x at the 
moment). FYI, the 3.12 brings performance improvements to Nouveau too.

What I wanted to say is that adding good fw support usually spans across 
multiple kernels. Even 3.13 has kepler fw fixes IIRC and 3.14 will 
receive some more updates to support new chipsets. It isn't a binary 
thing so this is hard to tell we support a feature...

I guess we could tell when is the first free implementation (with the 
possible fallback of using the blob's firmware[1]) and then when we 
added support for all chipsets of the family and it has been 
fairly-extensively tested and bug-free. Some cards would never pass the 
test though :s
