I do have a radeon_bl0 symlink inside /sys/class/backlight/ pointing to a valid path: /sys/devices/pci0000:00/0000:00:01.0/drm/card0/card0-eDP-1/radeon_bl0
I do not use systemd.

Handling of radeon_bl0 is probably an the issue for *another* subsystem, most probably Xorg, udev or ACPI (= the same package that currently handle the acpi_video0 file (which one is it?)
