Yeah, the open drivers don't matter a whole lot. It just loads the closed source proprietary blob into the gpu. It's a step in the right direction but can be very misleading.
The good news is that with the new open Linux kernel drivers from NVIDIA, Nouveau folks will be able to use the same signed proprietary firmware as the proprietary userspace component of the NVIDIA drivers. So that should unblock development of the open userspace component of the libre Nouveau drivers too.
