Gap 5: virtio IRQ handler at virtio/mod.rs:366-403 already reads
VIRTIO_GPU_EVENT_DISPLAY and calls refresh_connectors. Scheme layer
queues the hotplug event so userspace libdrm clients get notified.
Gap 8: atomic_check now validates connectors via the
available_connectors parameter — fixed in commit 32993a9ee.
