The variable seems to not be in that file any more, but I haven't had the time
to look into when it was removed.
The log is as follows:
WARNING: (guile-user): imported module (guix build utils) overrides core

With regards to the invisible LUKs prompt; my laptop does not run libreboot,
but is still affected. Seems more like the Thinkpad framebuffer driver has a
bug on the Linux or Grub side to me.
I can reproduce this on kernels 6.1.58, 6.5.7. Rolling back to a generation
with kernel 6.1.57 fixes it, though, this is a correlation and I do not know if
the kernel necessarily is what caused it.
As far as I know, the double prompt is expected behaviour (65002 seems to have
a fix for that),
