It's been a minute, but I did run OpenBSD on an X230 for a while- and I really enjoyed that rig when I had it running.  At the time, X220's were even better supported.  I believe the trackpad was even functional (with some fuss) as I remember, (which was *rare* at the time).  Synaptics - never not a fuss- grrrr.
(I didn't live with that rig for long, I was doing ZFS/jail hacking at the time, and swtiched that laptop to run FreeBSD - and X230 hardware was far less supported at the time.  Gave up audio and fast video to hack on my project at the time.)

As I remember that little laptop with OpenBSD: audio worked without fuss, (headphone jack and all), video was quite pretty, and Chromium was a new port so I do remember being giddy watching youtube high-def stuff...

Have fun with that rig!
