trackpad not working on Laptop NetBSD 11

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

Hello,

I did a fresh install off NetBSD 11.0 on an older Acer Aspire 520 which 
has a trackpad.
I had no previous older install of NetBSD, so I cannot say if it is a 
regression.

I noticed I haven't a mouse in X11, but if I attach an USB mouse it works.

In dmesg I see this:

[     1.035543] pckbd0 at pckbc1 (kbd slot)
[     1.035543] pckbc1: using irq 1 for kbd slot
[     1.035543] wskbd0 at pckbd0: console keyboard
[     1.035543] pms0 at pckbc1 (aux slot)
[     1.035543] pms0: autoconfiguration error: Failed to initialize an 
ALPS device.
[     1.035543] pckbc1: using irq 12 for aux slot
[     1.035543] wsmouse0 at pms0 mux 0


Is the reason at kernel-level driver or do I have only an X11 error and 
that pms0 error is perhaps not fatal?

Thanks,
Riccardo
