It feels like the series is short a patch :) As a side note, I did (many moons ago) propose a change to alter profiles used depending on AC/battery mode (in the thinkpad driver), and it was rejected as something that should be done in user space. Your use case does seem somewhat different, but it's similar enough that if you get it working I'd be interested to see if I can take advantage of the approach too. Mark |
