  * This code has been modified to match what is in the actual SCO X server.
  * This greatly helps inter-operability between X11R6 and X11R5 (the native
  * SCO server). Mainly, it relies on streams nodes existing in /dev, not
  * creating them or unlinking them, which breaks the native X server.
+ *
+ * However, this is only for the X protocol. For all other protocols, we
+ * do in fact create the nodes, as only X11R6 will use them, and this makes
+ * it possible to have both types of clients running, otherwise we get all
+ * kinds of nasty errors on startup for anything that doesnt use the X
+ * protocol (like SM, when KDE starts up).
