Wellm in principle all device mapper devices can be partitioned but in
practice very few are. Can you wait until the map type detection code is
in, we can then decide by map type what to do and treat linear and crypt
devices as unpartitioned (which is what you probably wanted to achieve):

+#ifdef ENABLE_DEVICE_MAPPER
+        } else if (dev->type == PED_DEVICE_DM && dev->dmtype &&
+                   (strcmp(dev->dmtype, "linear") == 0 ||
+		     strcmp(dev->dmtype, "crypt") == 0) {
+                strcpy(result, dev->path);
+#endif
