It is a Lenovo BIOS issue. Which doesn't mean we can't do anything about it (besides asking Lenovo for a fix), but I am not sure of what. It is probably best if thinkpad-acpi switches the ThinkPad to ACPI brightness mode, and report this on syslog... but I have to think about it first, and ask around for a bit. BTW, if I was sure it was a better idea to use the ACPI video interface before, I am more even so now. Depending which adapter (acpi video 0 or 1) you use it on, it does a lot of weird stuff, including checking the state of the AC adapter and using that for something, plus it uses a new UCMS (CMOS) command, 0x16, which I have no clue about. -- "One disk to rule them all, One disk to find them.
