dri config to work it around.
I spent some more time toying this around and I found that, building
the drm inside the kernel like in this extract of the config, and
provided that you still blacklist the amdgpu module:
BOOT_IMAGE=/kernel-genkernel-x86_64-4.17.2+ root=/dev/mapper/bee-root ro dolvm
crypt_root=/dev/sda3 real_root=/dev/bee/root resume=/dev/bee/swap iommu=pt
intel_iommu=on kvm-intel.nested=1 apparmor=1 zswap.enabled=1 security=apparmor
crashkernel=256M modprobe.blacklist=amdgpu
The kernel booting will ignore my evil purposes:
# dmesg|grep amdgpu

Technically it seems to be a weird workaround and I don't know if that may
light your bulbs in any way, but hey, I hope it helps.
