If this is true, it simply means you can say bye-bye to brightness support on thinkpad-acpi for the x61/t61 and later, there is only so much breakage I will tolerate before I decide they do NOT care about it and will keep breaking things further and further, and just drop the support. But we will only know this for sure after adding support for 16 levels, so it is early to get worked up about it. > One other point: when thinkpad_acpi gets out of sync, issuing a ...
