Well it took me a bit longer than I said, but I finally tried it :)
My config is attached. Hackily, I copy-pasta'ed the kernel packages
entirely from guix v0.9.0's release. I can confirm that this can read
the hardware clock just fine, whereas the other version of the kernel
can't... so it does indeed look like between Linux-Libre 4.2.5 and
Linux-Libre 4.3.3 we have some sort of regression that leads to this
problem on x200 Minifree Libreboot-enabled laptops, at least.
