Always read the thinkpad-acpi docs, people :-)  I keep it up-to-date.

thinkpad-acpi not yet supports the brightness stuff in new thinkpads.

BTW, probably you *will* have to make peace with the video module sooner or
later.

Look at the -latest- thinkpad-acpi docs, search for brightness_mode.  It
should have a fix for *that*, at least.  But it should also be activated
automatically in anything Lenovo... are you using the very latest
thinkpad-acpi from ibm-acpi.sf.net?

Good luck. thinkpad-acpi cannot help you there yet in very new thinkpads, if
it doesn't work out-of-the-box...
