Also X1 Carbon and T4XX series, for light/small laptop types, to say nothing of other X-series ThinkPads. I found a guy on Twitter recently, Roman Zolotarev, who runs a small job board and documents OpenBSD installation, configuration, and so on, for X1 Carbons in excruciating detail -- and apparently the detail is well beyond the needs of the typical install because X1 Carbons are evidently very well supported. My own T4XX is also very well-supported, as are those of other people I know personally who bought ThinkPads in that series for use with FreeBSD and OpenBSD after hearing about my positive experience.
