I have an x200s, which is a slightly different machine.

I'm using the BIOS that came with the computer when I bought it
second-hand; it appears to be from Lenovo. I don't know whether or not
the differences in our hardware would cause this issue. And like I said
before, this used to work for me.

I see the same:

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

I keep the system up to date, but it's not usually "vanilla" `guix
pull`. I normally reconfigure the system from a Git checkout, and
sometimes it has custom patches, or I use the core-updates branch, or
other things like that.

However, the problem is consistent, and it persists when I try using
Guix straight from `guix pull`, version 20161114.22.
