I’m not familiar with FreeBSD enough to help debug. This would need to be a question for the FreeBSD experts.

Other things like keyboard, trackpoint, LCD brightness, keyboard illumination are working. Not sure if relevant, but I noticed that WLAN LED (for replacement Atheros card) doesn't light under FreeBSD with coreboot/SeaBIOS. I'm not sure what that means in the context of FreeBSD. Can I somehow try to debug it? Or use ACPI dump from Linux or stock BIOS under FreeBSD? Recompiling kernel and/or reflashing BIOS is not much of a problem :)help
