I do, but FreeBSD doesn't have the needed WMI doodads to interact with
this, nor do I have the needed Dell laptop doodads in the kernel to test
otherwise.
To get /those/ working will require something else entirely. I have been
looking at the Linux drivers:
https://github.com/torvalds/linux/blob/master/drivers/platform/x86/dell-wmi.c
https://github.com/torvalds/linux/blob/master/drivers/platform/x86/dell-laptop.c
I'll save those for another day though, this is a bit off-topic. If
anyone else has laptop keys I'd like to see how they interact too.
