Can you wait just a little bit? Till end of month two Dell kernel devs are on vacation, so after that they maybe answer to question about new hotkey format/support in kernel.

I do not like name "dil". It takes me few minutes to interpret it as Dell Instant Launch...
Also I do not know if this is the best approach.

I'm trying to figure out if those two keys are really reported via keyboard controller or not. They were added 4 years ago in commit f1566f0dc07ec9b5409b348070f5a700032d7881. But from bug report http://bugs.launchpad.net/bugs/815914 there is no information if those two keys are really reported by keyboard controller or not.
And if not our problem could be easier...
