The basic touchpad stuff works after resume, it is only the right corner 
tap thing which stops working.

This is the scary and ugly thing which I was afraid of originally (it is 
off-topic here, but I don't like HAL). So I have this in my .bashrc 
 
synclient RTCornerButton=2

and so far it worked fine. If possible, I would like to keep it that
way. But I will test the HAL config above too.

Yes, I will do it.
