By default, X11 uses /dev/mouse, I think. So perhaps there is just a symlink /dev/mouse -> /dev/ttyS0 missing. (Of course, you have to refer to the correct mouse device, /dev/ttyS0 is "COM1", so if you have a bus mouse, you will have to change this to the appropriate device.)
So doing something like this (as root) ln -sf /dev/mousexyz /dev/mouse will do the job.
