Yes and no. 1.9.6 is in linux-firmware.git. I've tried to add 1.9.9 too
but that failed.

Sure, but this could be a different patch then. I think Intel devices 
(iwlwifi, iwlegacy and ipw2x00) have a similar text about "download
firmware from this device from our homepage here" too. So if we want,
we can remove them altogether?
