We need reports for several machines, so that we can know the same internel LED ID was not used for different leds across different machines. > Can we somehow rename it for this particular case from tpacpi::unkown_led > to tpacpi::fn and mark it as 'safe'?

It is not impossible to do it, but we'd need a proper map of leds across the several newer models to know how to do it sanely. i.e. update http://www.thinkwiki.org/wiki/Table_of_thinkpad-acpi_LEDs -- "One disk to rule them all, One disk to find them.
