Thinkpad t460 acpi issues

[Softwafe Engineer]

Hello.
Freebsd 13 rc3

I'm trying to enable acpi hotkeys on my thinkpad t460 but
unfortunately looks lite it unsupported.
I've loaded acpi_ibm and acpi_video but only three hotkeys works (on
my laptop it's fn+F(number)).

As well I noticed strange behaviour on closing laptop cover. When I do
it then laptop starts to increase funspeed and no keys or trackpad
reaction after opening. Only reset works (long pressing on power
button).

Is it possible to add supporting for my laptop?
