Serial mouse requires the following setup:

1. /etc/XF86Config must define the Protocol and Device correctly.

I've used:
Protocol "Microsoft"

successfully with a Logitech Serial 3-button mouse

2. /dev/mouse must be linked to the correct device, or must have
the same major/minor as the correct device.

I've done both, but typically:

XF86Config has: Device "/dev/mouse"

ln -s /dev/ttyS0 /dev/mouse

The above should at least make the correct connection. Note that you might
have to modify the "Protocol" in XF86Config for the particular mouse you have.
The Logitech mouse I have didn't work correctly with Protocol "Logitech", but
does with "Microsoft".
