Catalyst for what?
The drivers in consoles are not developed over the OS because there are no concurrence between OS and Games for the GPU... the driver have direct access to GPU to avoid overhead present in PC drivers.
In fact you only loss performance using the Catalyst.
Even Xbone didn't use the Catalyst like it was on PC.
And FreeBSD is a obvious choice... any change that Sony do in Linux they need to release the source code to public but the BSD lincense allow that Sony merge open souce code with proprietary code without release the source to community.
