A quick follow-up that will hopefully make a fix a bit easier: On the advice of jcs@, I first tried https://github.com/jcs/intel_backlight_fbsd which was able to adjust my backlight fine once I rebooted with machdep.allowaperture=3
Next, I booted up with acpivout disabled (from boot -c) and after that, xbacklight and wsconsctl can both properly adjust the display brightness. This is in 6.1-STABLE.
