Depends on distro specifics. Also the firmware has to be available at the time that nouveau loads. The corollary to this is:
If it's built into the kernel, then the firmware must also be included in the kernel (since this happens before any FS stuff) If it's loaded as a module from initrd, then initrd must contain the firmware
If you need help including firmware in the right place, a distro support channel is probably your best shot.
