Is there a good way to snoop on wsmouse and figure out whether or not
it's seeing anything?  I'm debugging multiple-button support in VirtualPC.
I had it working once, but I can't get it working now... Anyway, what I'd
ideally like to do is poke around and figure out how many buttons wsmouse0
thinks it has, and whether or not it's getting any events...

I'm seeing

pmsi0 at pckbc0 (aux slot)
pckbc0: using irq 12 for aux slot
wsmouse0 at pmsi0 mux 0

so it *thinks* it has a scroll wheel, but no events from the extra buttons
seem to be coming into X at all.
