   Then you must also have some application logic that will call
-  up_simtouchscreen(0) to register the touchscreen driver.
+  sim_tcinitializ(0) to register the touchscreen driver.
 
   NOTES:
-  1. If you do not have this call, the build will mysteriously
-     fail claiming that is can't find up_tcenter(0 and up_tcleave().
-     That is a consequence of the crazy way that the simulation is
-     built and can only be eliminated by call up_simtouchscreen(0)
-     from your application.
