+         This driver provides support for virtio based paravirtual device
          drivers over PCI.  This requires that your VMM has appropriate PCI
          virtio backends.  Most QEMU based VMMs should support these devices
          (like KVM or Xen).

+         This option enables building a transitional driver, supporting
+         both devices conforming to Virtio 1 specification, and legacy devices.
+         If disabled, you get a slightly smaller, non-transitional driver,
+         with no legacy compatibility.
+
+          So look out into your driveway.  Do you have a flying car?  If
+          so, you can happily disable this option and virtio will not
+          break.  Otherwise, leave it set.  Unless you're testing what
+          life will be like in The Future.
