Brightness events are handled in firmware (and no, you cannot make the firmware NOT handle it) in IBM thinkpads. Lenovo thinkpads seem to be moving it to userspace, so you have to generate the events and actively handle them in the ACPI OSI or in userspace. I generate events *only* for stuff that needs active handling by default. Since the hotkey mask cannot really be trusted to filter out events (unless I start filtering it in the driver *as well*... might be a good idea), I don't add the passive keys to the keymap. Regardless, userspace *will* have to take some action to enable the hotkeys that are to only be used for passive monitoring. Right now this means enabling them in the mask, and remapping the key map. If this is that a big problem, I can add extra driver filtering, and make it only "enable it in the mask". -- "One disk to rule them all, One disk to find them.
