Brightness/volume controls for the Lenovo X230

[Adrian Chadd]

Hi,

Now that the pkg.freebsd.org stuff has updated drivers and I'm running
with the new xorg/dri2 code, all the basic things that irked me with
suspend/resume are now fixed. The other issues (softclock panics) are
something I'll chase down myself.

Now for the niggling bits.

What was the end result with all the digging done for handling button
presses for the x230? I'd like to finish off a few things:

* usb camera
* brightness controls
* volume controls/mute (button+led)
* microphone control (on/off button+led)

Thanks!
