Attaching a patch to get keyboard backlight working on new-ish(?) thinkpads , such as Thinkpad T14 Gen2. Probably works on other newer thinkpad models.
Patch is based on https://reviews.freebsd.org/D14103 which seems to be in limbo since 2019. The keyboard stuff backported and tested on FreeBSD 15.1RC1.
Quick usage instructions:
In /usr/src/sys/dev/acpi_support patch acpi_ibm.c
In /usr/src/sys/modules/acpi/acpi_ibm build and install
Unload acpi_ibm and load the new one from /boot/modules (kldload /boot/modules/acpi_ibm.ko)
sysctl dev.acpi_ibm.0.kbd_backlight=1
Now you can type with confidense.
