There's a lot more firmware files than that ... everything in the
gp107 directory. Also this would only be necessary if nouveau is built
into the kernel. The files just have to be available whenever nouveau
is loaded -- if it's built in, that means the firmware has to be baked
into the kernel too. If it's loaded from initrd, that means the
firmware has to be in initrd. If it's loaded after boot, then the
firmware has to be available after boot.

Cheers,
