I my case it seems the issue wih the keys is that FreeBSD doesn't really
"know about them".

In the Acer laptop, it compiled and installed fine, and after reboot the
sysctl works awesome, but I add to map the keycodes in fluxbox:
None 239        :Exec   intel_backlight decr
None 123        :Exec   intel_backlight incr

I use the intel_backlight program still cause its easier to send the "decr"
and "incr".
