Rubenerd: FreeBSD brightness controls on Panasonic laptops

I have a longer post about my “new” Japanese Panasonic CF-SZ6 laptop pending. But in the meantime, you can enable Yamamoto Taku’s acpi_video(4) driver to get backlight controls on your function keys:

sysrc kld_list="i915kms acpi_video"

Older Japanese Panasonic laptops used Ogawa Takaya’s and Takahashi Yoshihiro’s acpi_panasonic(4), which I assumed was required but broken on these newer machines. I’d written my own devd wrapper scripts around intel_backlight, before realising they implement generic ACPI drivers. Whoops!
