Thanks for checking. I spent a little time this morning trying to walk through
the ASL as attached to the Bugzilla entry and I think this is the correct approach.

JÃrÃme,
I have one question though. These events should be happening as a pair.
Press: 0xCE, Release: 0xCF.
What happens with the event on power button release?
Is that showing a message in the log during wakeup from S2I?

Something like "unknown event 0xCF"?
If so, it would be good to also catch and ignore that too.

Thanks,
