   You can buy adaptors that do this or make your own (the logic is
very simple. see http://cvs.anu.edu.au/monitorconversion/sun.html).

   Sync on green monitors, however, are not so simple because the
logic modifies the green analog signal which makes this a high
frequency circuit.  I made a circuit to do that once and had it
on my old web page back in college - long gone.

   Somebody like Marc La France would have to address that.
I don't see an option for it in the radeon driver.

   I don't know if the 13W3 adaptors have a power line in them.  In
order for the *cable* to do the sync combining I think it would need
active electronics in it, which means it needs power of some sort.
So I'm suspicious about the ability of a dumb cable alone to handle
the sync combining.
