What about firmware? Do we know which AMD Radeon cards, if any, can be used without including nonfree software in the OS? A quick web search would seem to suggest that on Debian, it is very commonly required to install the 'firmware-linux-nonfree' and/or 'firmware-amd-graphics' packages from non-free. Thanks, Mark
