The radeon driver requires nonfree firmware. This is the core issue which is not going to get fixed anytime soon. There appear to be partial fixes for some cards, for example I see mailing list threads like https://www.fsfla.org/pipermail/linux-libre/2015-July/003080.html Xorg on fbdev fails on Guix but works on other distros with 800×600 resolution at 75 Hz for my AMD GPU.
