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! :-)
