Very nice. I am currently looking for some info to solve a problem with
thinkpads and logitech cordless mice over ps/2. Basicly the wheel doesnt
work. Looking closer they dont respond to the imps/2 or mousemanps/2
protocol. Since cordless mice are more common than thinkpads, I think the
problem would be solved if it was with the mouse. So I am guessing the IBM
defaults to just repeating standard ps/2 protocol, and you have to first
trick that before you trick the mouse. Since it works in windows there IS a
way...

Where do I find the public available protocols, and the secrets? :)

And for the list, who should I notify that I am working on autodetecting IBM
thinkpad ps/2 repeaters in mouse driver?

(And yes I know some of the work belongs in XFree and gpm)
