Current for OpenBSD 5.2-CURRENT (4 November 2012)
This Lenovo x200s was purchased on eBay in November 2012. The main reasons for purchasing this laptop was it's support by OpenBSD, long battery life, small size, ample screen resolution, and support for sleep/suspend.
Here is a full dmesg.
The basic hardware specs of this laptop are as follows:
The CPU is an Intel Core 2 Dual L9400 running at 1.86GHz.

The Intel GM45 video chipset is fully supported by the X11 drivers.

This Intel wireless card does require a binary firmware blob from Intel in order to operate.
While the volume is a bit weak on this laptop due to the small speakers, sound works fine.

The fingerprint scanner on this particular Lenovo is not supported.

The x200s does not have a TrackPad. It's sole pointing device is a TrackPoint with three mouse buttons.
All hardware buttons such as the volume keys work fine and OSD feedback under X11 is provided with the "tpb" package. The blue Access IBM button is programmable with the "tpb" package. I have mine programmed to put the laptop to sleep quickly.
Most of the Function (Fn) modifier keystrokes such as Fn+Home/End (screen brightness), Fn+PgUp (ThinkLight), Fn+F4 (sleep / suspend to RAM) all work. OSD feedback under X11 is provided with the "tpb" package. The BACK/FORWARD buttons near the cursor key cluster are programmable with the "tpb" package or xmodmap(1).
APM works fine with apmd(8). apmd(8) and apm(8) work to automatically or manually control the speed of the CPU.
Suspend to RAM (sleep) with zzz, apm -z, or Fn+F3 works fine. Suspend to disk (hibernate) does not currently work.
The ThinkLight keyboard light works great!
