Two days ago Andy Ritger and Christian Zander were interviewed by BSDTALK http://bsdtalk.blogspot.com.

In this short interview NVIDIA developers were supposed to talk about FreeBSD drivers.

Fortunately they also talked about driver as whole. So we can hear about development process, interaction witch other developers and even what part of driver they develop(and many more). There is answer why they started development of UNIX drivers(42).

In short this interview answers many question. But as this is about FreeBSD there was not enough time to talk about other operating systems in detail.
More information can be found in interview:

ps.
So maybe Phoronix can also interview them?
And allow readers(of Phoronix) to choose questions.(It's just an idea)
