Ah, but I'm not worried about testing on a touchpad-only laptop,
we are already reporting a trackpoint there even though there
is none. I'm worried about breaking existing v7 using laptops
which actually have a trackstick.

So if this is tested on a v7 laptop with trackstick, and it
does not break the trackstick then that is good enough for me.

Regards,

Hans
