   SyncOnGreen, yes, but I'm not sure about Composite Sync.  Their
hardware can do composite, I'm pretty sure, but I don't recall any option
to turn that on in the driver.  Composite Sync is a trivial external
electronic circuit, however.  Sync-on-green is not so trivial due
to the frequencies involved (it messes with the analog data and 
naive approches will give you visible artifacts). 

                                Mark.
