MMIO registers are handled by a different layer than the virtio console itself. After the virtio refactoring in QEMU, they will be completely separate drivers.

Good point -- we don't really want to be mixing up the transport and the backend. You can see it in the kvmtool patch, in fact -- it introduces an "if this is virtio-console" special case into the mmio.c file which previously was entirely backend agnostic.
