Hm. I /suspect/ that these would be better handled by a quickplay button 
driver. There's a patch for that lying around - I'll try to get it 
updated.

Ok, so again handling them in hp-wmi is probably not a good idea.

Since they're going through the keyboard controller, we should probably 
ignore them.

Again, looks like these are going through the keyboard controller. 
Thanks for the feedback, I'll try to work out a way of avoiding printing 
the messages.
