Henrique, thank you for your speedy and informative reply.

I'm happy to open a tech support request with Lenovo. Do you have a suggested description of the issue? How should I present this so that it will not simply be dismissed as an issue with unsupported software that is not Lenovo's responsibility? Regarding the other glitches, Henrique wrote: > They are known kernel ACPI video.c bugs, which are going to be fixed. OK, that's good to know. Sounds like for now my best strategy is to add "blacklist video" and "options thinkpad_acpi brightness_enable=1" to my modules configuration. I'll work on chasing down any other glitches within that configuration only.
