+	  Adds support for the Intel Volume Management Device (VMD). VMD is a
+	  secondary PCI host bridge that allows PCI Express root ports,
+	  and devices attached to them, to be removed from the default
+	  PCI domain and placed within the VMD domain. This provides
+	  more bus resources than are otherwise possible with a
+	  single domain. If you know your system provides one of these and
+	  has devices attached to it, say Y; if you are not sure, say N.
