Good to hear.

I think it is fairly clear: no licence is available for the firmware,
therefore it is being illegally distributed by netbsd CVS, kernel.org
and the alsa people.

Since the firmware is not distributable you should remove the pre-built image.
Then make the scripts check all known places for downloading the
firmware and extract from whichever is available in case they get
removed. Also try to find where cwcealdr1.zip originally came from so
that if the alsa folk remove it then there is still a source for it.
