Serial mouse problems with Xubuntu install

[squareyes]

Hi all,
am experimenting with Xubuntu on an old 166 machine.
I installed the base system, and then installed Xubuntu desktop,
but using sudo dpkg-reconfigure xserver-xorg, cannot get it to
recognize the serial mouse. Only has 2 varieties of ps2 as option
Knoppix recognizes mouse, but is a little s  l  o  w, no it's extremely 
slow :-)
"Mouse is ECM:0001
Have I missed something in the install??

Thanks in advance,
Take Care
