This is perfect (I mean, not that it still doesn't work, but that we
have some error output). I think I know what's going on. The new 'guix
system reconfigure' uses G-Expressions, and it looks like Grub is being
ungexp'd for the wrong architecture. To be sure, what's the architecture
of this machine?

I'll investigate further and let you know what I find. Thanks again for
doing this.
