I have doubts about the text (for me) complex of this license
http://www.acpica.org/downloads/unix_source_code.php Free?Not that I'm one to make an official qualification of anything, but I don't see anything immediately nonfree in there. It appears to be more or less X11-ish plus an export clause. The export clause makes it GPL-incompatible, but not nonfree. Perhaps others here will spot something more problematic. Or maybe debian-legal or others have already researched it? Best, Karl
