dmesg output

Dear Madam/Sir,

Wishing You & Your Family "A Very Happy New Year".

I am trying to install FreeBSD 14.2 on lenovo thinkbook 14-IML and have not
been able to get the trackpad to work. I am enclosing the dmesg output for your
kind perusal.

The trackpad is a multi-touch touchpad, buttonless touchpad Touchpad Buttonless
Mylar® surface multi-touch touchpad. I have tried to get the drivers installed
and the commands
/sys/dev/atkbdc/#grep 'Single Synaptics on Active Mux' psm.c and
sys/dev/atkbdc/#grep 'enable_single_synaptics_mux' psm.c
Despite these the trackpad is not detected using the command
dmesg |grep psm

Could you please guide me how to have these work.

Warm regards,

Prashant
