I see nothing in the XFree86 v. 4.x docs about _simultaenous_ support
for multiple mice. Mouse support docs are here:
http://www.xfree86.org/4.0.1/mouse.html

KGI is a software interface in the kernel, for communicating with
hardware. libggi (which implements the GGI notion) is a set of routines
to speak to KGI, libX11, and some other software interfaces for hardware
communication.
The Berlin project uses GGI as its interface to hardware (and thus
operates through KGI in the kernel).

Just to confirm: Your URLs cast no light (as far as I can tell) on how
to do multiple, simultaneous mice on XFree86 4.x.
But who knows? David Madison (_not_ Ian -- sorry) might be able to play
around with those techniques and make it work with his PS/2 and serial
rodents.

Subject: [svlug] Two mouse solution
After wrangling for an hour or so, I figured out how to get *my*
two mice to work, you probably wouldn't want to use this for a
graphics tablet since I've used gpm, not Xinput as my solution
(since I couldn't get Xinput to work properly :)
The trick I used is to use the gpm repeater function. gpm is the
daemon that handles the mouse for virtual consoles, but you can
'repeat' the mouse information into the /dev/gpmdata pipe, and gpm
can handle multiple mice (and even remap buttons :)
So I start up gpm:
% gpm -k # Kill the gpm daemon
% gpm \ # And restart it..
-R MouseSystems \ # repeat to gpmdata as MouseSystems
-t ps2 -m /dev/psaux \ # first mouse, PS/2
-M -t ms -m /dev/ttyS0 -B 132 # second mouse, serial, switch buttons
Then I configure X to use the repeated data as if it
were a MouseSystems mouse, as specified above:
# File: /etc/X11/XF86Config (or /usr/X11R6... or..)
--------------------------------------------------
Section "Pointer"
Protocol "MouseSystems"
Device "/dev/gpmdata"
--------------------------------------------------
Now I have to setup my laptop the same way for different mouse reasons.
I'm surprised that more people don't run into multiple mice difficulties.
As a side-note, I couldn't get Xinput to work, though I didn't read
all the docs.. Here's my failed attempt:
--------------------------------------------------
Section "Xinput"
SubSection "Mouse"
Port "/dev/ttyS0"
DeviceName "Mouse"
#Mode Relative
AlwaysCore
Protocol "Microsoft"
EndSubSection
EndSection
--------------------------------------------------
If anyone familiar with Xinput can see any obvious problems, I'd love
to know for future reference.

Below are the relevant sections from my XF86Config.
It's been a few months, so I don't recall exactly why I did this.
I may have set up the USB trackball in the Pointer section if I
couldn't get Emulate3Buttons to work under Xinput. Also, I think
I needed both ps2Mouse and ps2Core in order for the PS/2 side to
work...
I gave up running gpm because I couldn't get the two mice to coexist
in gpm. IIRC, gpm couldn't deal with the dead USB side after doing
a suspend-to-RAM followed by a resume. XF86 just ignores it until
I rmmod/insmod the USB driver (usb-uhci in a K7V/Athlon machine).
(I got the Marble Mouse trackball because I didn't have a space
within easy reach where I could put a regular a mouse; I leave the
trackball perched on top of the numeric keypad. I could never get
used to the thumb-driven trackball on the Cordless TrackMan Wheel.)

I tried it again, and it seemed perfectly happy with just the ps2Mouse
definition. So here's the revised XF86Config incantation:
