How to set up PS/2 mouse?

Hi,

I just installed the NetBSD system on my very old Toshiba Satellite
2540CDS laptop.

I am using so far the virtual consoles.

I want to use the PS/2 mice which is an
Integrated Pointing Device: AccuPoint.

It is phisically between keys on the keyboard.
It seems as a little green button, but which can be moved as one move
a joystick: in all horizontal directions.

On the handheld of the laptop there are two mouse buttons.

That is about this mice.

On Debian system I was used it as a PS/2 mouse and used it with gpm.

I searched the Google for the solution, but not found any advices.
Here, on my NetBSD system there is no /dev/psm devices at all.
If I run the command:
moused -p /dev/psm0
I get this message:
moused: unable to open /dev/psm0: No such file or directory

How can I set up this mouse here, on the NetBSD system?
