Dear Maintainer, I'm currently running an installation from 8.0.4-amd64 CD and can confirm that this bug still exists. I had to apply the workaround described above to make installation work.
BTW, information in Debian Wiki <https://wiki.debian.org/Firmware> is outdated. The text talks about tarballs, but <http://cdimage.debian.org/cdimage/unofficial/non-free/firmware/> only holds .deb files. Now watching 8.0.4 install on my venerable X61s... Cheers Jan
