Ok, with those, I don't have the recursive fault nor the thinkpad-acpi warnings.

I get the “crippled” behavior: no brightness keys without userspace daemon. With a userspace daemon (xfce4-power-manager) it works fine (I get only 10 brightness levels but that's will indeed depend on what daemon you use).

I still get a warning in the logs though:

Jul 17 15:16:51 balvenie kernel: [ 182.606930] ACPI: Failed to switch the brightness

which I guess is expected since ACPI doesn't handle the brightness.
