Hi, I took a brief look at the upstream website. The download site [1] points to two other pages for downloads ([2] and [3]), one of them having the non-free license, the other a BSD/GPL dual-license. Interestingly both of these ask to accept the non-free license...
They both contain a different link to a source tarball. I downloaded both and compared them: they only differ in the license headers in the individual files. The files in acpica-unix-20130214.tar.gz have the non-free license. The files in acpica-unix2-20130214.tar.gz have a 3-clause BSD license or GPL-2: ---- * Copyright (C) 2000 - 2013, Intel Corp. * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
