Public bug reported: The Fn+Brightness keys on the Samsung NC-10, which need a quirk to work, did not work with any Oneiric kernel until 3.0.0-15. This appears to be because (according to the Changelog) a quirk was added to that version. Previously, I had been using the latest natty kernel, which continued to work.
Unfortunately, though I can see nothing relevant in the Changelog, 3.0.0-16 breaks this functionality again: the brightness controls allow only the minimum, minimum + 1, and maximum brightness levels to be set, but nothing intermediate.
