Mika, do you see any problems with disabled (deferred?) interrupt for this type
of event? I think it might break the suspend-resume (on touchpad event). Also
do you remember if we ever had touchpad event to be ActiveBoth?

What I'm trying to understand if this is pure BIOS issue (typo) or HW really
wants to
- be able to generate events to the OS (at boot time?)
- have the reaction on any edge

Mario, do you know anything more? It's AMD platform at the end, what the TP
model and if it requires both edges...
