To speed up the fake timer, just use

diff --git a/present/present_fake.c b/present/present_fake.c
index 2350638ea..faff0e310 100644
--- a/present/present_fake.c
+++ b/present/present_fake.c

      */
-    if (screen_priv->info && screen_priv->info->get_crtc)
-        screen_priv->fake_interval = 1000000;
-    else
-        screen_priv->fake_interval = 16667;
+    screen_priv->fake_interval = 16667;
 }


The real challenge would be to recognise that the window is only on the slave
output (on a different Screen than PresentPixmap was called for) and pass along
the request. Then you have the challenge to make sure that any drawing
operations go back to the master/slave again.
