This applies to the Guix System installer in git master *without*
patches.

Deniz at Parabola GNU/Linux-libre discussed a similar issue for
Parabola today:

  Here what would need to be publicized would be how to blacklist the
radeon driver at boot, in the case something goes wrong and the user
is left with a black screen during the boot of linux-libre.

  On Parabola adding "modprobe.blacklist=radeon" to the kernel command
line does that at boot. This enables users to easily use the
installation medias.

Deniz also wrote that this would break HDMI, but HDMI does not work
for me in the Guix installer anyway (but possibly it worked for
others?)
