Lenovo T60p touchpad not working (6.2-stable/amd64)

Jonathan Thornburg-3
I have a Lenovo T60p laptop (amd64) currently running 6.2-stable (dmesg
below).  I last rebuilt from source on 2017-12-15, but a cvs-update of
/usr/src today (2018-01-10) shows no changes, so this machine is fully
up to date for -stable.

My problem is that the touchpad does not work: finger movements on the
touchpad either have no effect on the X cursor, or sometimes result in
small movements of the X cursor which are not proportional to the finger
movement.

For what it's worth, this same computer has in the past had its touchpad
'just work' under OpenBSD 4.9, 5.1, 5.4, 5.6, 5.8, and 6.0 (all initially
-release and then -stable).

As a temporary workaround I have plugged in a USB (wired) mouse, and I
was delighted to see that it 'just worked'.  What's even more peculiar
is that _when_the_USB_mouse_is_plugged_in_ the touchpad works again!

Any suggestions for reviving the touchpad (without plugging in a mouse)?

Here are the dmesg for booting without a mouse plugged in (/var/run/dmesg.boot),
then the dmesg after pluggin in the mouse and unplugging it once or twice:
# cat /var/run/dmesg.boot

Amendment: when the USB mouse is plugged, the touchpad *sometimes*
works again.  And sometimes it doesn't (finger movements on the touchpad
are ignored again).

Hi,

Quite the same appears here on a no name laptop with stock 6.2 kernel.
Pms0 disappears when booting in uefi mode. And not when booting in mbr
mode.
Strange and funny.

A further update... after a suspend-resume cycle (suspend-to-RAM,
which 'just works' via Fn-F4), the touchpad works fine.  'dmesg' shows
15 new lines appended after my most recent suspend-resume cycle, but
none of them mention the mouse (pms0) explicitly:

Do other T60/T60p users see touchpad problems?
