When you only have S-Video plugged in, is the machine actually
hanging, or is there just no output on the TV? Depending on X, it may
be looking for a VGA monitor to be present to successfully launch the
X server. If this is the case, it is usually possible to edit the
xorg.conf file to tell X that you are using on S-Video output.
Alternatively, if you are using a clone mode, then it is likely it
will try and detect the presence of the VGA card first (which may
explain why it works and you get cloned displays with both VGA and
S-Video connected)

On my Pundit-R (ATI based) machine, I use only S-Video output
connected to the TV. I changed the BIOS to reflect this, and also
edited my xorg.conf file to tell it I am using only display via
