Hi Mark and Klaus,

Seems like the simple solution to firmware files moved from /lib to /usr/lib is
to modify the eudev (udev) rule to search both in /lib and /usr/lib. I have not
yet found out which program/rule does the actual installation of these firmware
files. Maybe you know?

Examples:
apt-file show firmware-realtek
firmware-realtek: /usr/lib/firmware/...

apt-file show firmware-linux-free
firmware-linux-free: /lib/firmware/...

apt-file show firmware-atheros
firmware-atheros: /usr/lib/firmware/...

apt-file show firmware-amd-graphics
firmware-amd-graphics: /usr/lib/firmware/...
