That may have been the reason, perhaps before the mouse driver was written to
the busmouse interface (not sure I have kernel sources dating that far back).

Yep, I do recall that - my intention was to reverse the logic in order to give
Geert (and myself) something to test while you add the necessary bits to
ARAnyM.
Such a hack would definitely be removed as soon as possible.

The original (and current) mouse driver explicitly set the top screen origin -
either at keyboard init (old) or at mouse device open (now). I do assume that
is
not the default, power-up state of the hardware.

Point taken - I'll not complexify things further by attempting to detect ARAnyM
at runtime, then. I have a patch that should work on both current ARAnyM and
real hardware for Geert to test, and the hack is easily removed later on.

How does that one work?
The only reason for reviving the joystick hack would have been to have a
'standard' way of passing a third mouse button. If the PS/2 adapter is that
standard way now, that's fine. I'll just need to know what interrupt/device
this
is hooked up to, and what the data format is.

I was mainly looking for a quick way to accomodate current ARAnyM users like
Geert and me while a fix is being worked on. I did read your mail, and take
notice of your offer to incorporate a fix for ARAnyM, even though I did not
refer to your mail in my reply.
I'd still have to get a working X server before testing any of this, so it
probably won't matter either way.
