This seems similar to the unfortunate situation with the b43 wireless
card firmware. Broadcom refuses to provide the firmware under a
redistributable license (or even as files separate from their
proprietary drivers). This did not stop b43 from being included in
Linux. Distributions have dealt with it by providing a script that
downloads the proprietary driver and extracts the firmware from it to
files in /lib/firmware.

Do you think that a similar solution for nouveau would be legally
problematic? Or is the issue technical, since you mention that the
ctxprogs were obtained by mmiotrace, instead of a more straightforward
extraction from the binary driver blobs?
