So, this morning, I updated my configuration to:

```
  (bootloader (bootloader-configuration
                (bootloader grub-bootloader)
                (terminal-outputs '(console))
                (targets (list "/dev/sda"))
                (keyboard-layout keyboard-layout)))
```

I reconfigured and rebooted and… got the following error right after
the "Welcome to Grub!" message:

"""
error: no video mode activated.
"""

I broke out in cold sweat and saw my life flash before my eyes…
but, after 2 seconds, the text menu showed up! \o/

Thanks for your help! :-)
