ers into how to proceed, so I can find
out why this Synaptics device doesn't get attached except as a "Standard
PS/2 mouse"?
Or does anyone know if it is possible to upgrade or downgrade the
touchpad firmware?

I will try and work out a solution that could perhaps be accepted as a
patch, perhaps based on a FLAGS value for pckbc to be used on
legacy-free machines. Suggestions are welcome.

had a similar issue recently on a Panasonic laptop of similar vintage.
It is related to the use of 'legacy-free' UEFI firmware, implementing
'Active Multiplexing' for multiple PS/2 AUX devices such as the Touchpad.
OpenBSD doesn't currently support Active Muxing for such devices. It was
implemented some time ago but then reverted due to compatibility issues
caused.
However, I was able to work around the issue by changing the Aux select
byte in i8042reg.h and building a custom kernel.
No guarantees it will work for you, but may be worth a try.
