The touchpad and TrackPoint work out of the box, but the physical buttons for the trackpoint do not. You will need to install.
If you would rather not install a recent kernel, there is a work around for Linux 3.19.2-ARCH. If you add
options psmouse proto=imps to
/etc/modprobe.d/x250.conf, you can force the mouse module to use a more basic protocol than the built in one for the TrackPoint, which needs a patch. The effect is that the touchpad and mouse are treated as one device, but synaptics is not supported. If you want two finger scrolling, for example, you will need to either deal with the broken TrackPoint buttons are install the new module.

Backlight and Keyboard
In order to get the backlight to work, I added
options thinkpad_acpi force-load=1 to
/etc/modprobe.d/x250.conf. This forces the thinkpad_acpi module to load, which is needed for controlling the backlight via as well as enable some of the extra media keys.
Although a dedicated Pause-key is missing, it can be input using the key combination
Sound and Volume Control
In order to get control of the audio from Intel hdmi, you have to disable it and force alsa to use Intel PCH. See ALSA#Set the default sound card to set the default sound card to Intel PCH (speakers and headphones).
options snd_hda_intel index=1,0
Withand installed, you can map the volume buttons to change the volume. Here are some samples:
event=button/mute action=amixer -c 1 sset Master toggle -q
event=button/volumedown action=amixer -c 1 sset -M Master 5%%- unmute -q
event=button/volumeup action=amixer -c 1 sset -M Master 5%%+ unmute -q
event=button/f20 action=amixer -c 1 sset Mic toggle -q
