If playstation 3 and 4 are a modified FreeBSD, and on the 4th version console the graphics are AMD that means they (sony and amd) have some sort of driver for this platform. And its not a bad one, because they chose AMD for play4.
Why that has not been release to the FreeBSD audience ? When is this expected to happen ?
Also, I would hope that Mesa drivers work on FreeBSD.
Note: these aren't the only examples of Sony contributing back to FreeBSD, they were just the easiest to find.
IMO, AMD would really need to be the one to contribute drivers back to FreeBSD.
This is BSD, so the authors want companies to be able to keep the modifications and drivers proprietary if they choose to do so. So in this case, its very much possible that the when is "never" and why is "money".
