Using OpenBSD on a thinkpad?

[crimeangothic]

Hey everyone, I am pretty stupid when it comes to less user friendly operating 
systems. I currently use slackware/windows and am thinking of using OpenBSD on 
either my thinkpad e420 or my libreboot t400. Are either supported(or at least 
possible to install on?) I’m sorry if this question has already been asked but 
I can’t really find any answers and the mailing list archive is barren as well. 
Thanks!
