Ah ok.  I think that's the same card benh was playing with last night.
 You are going to need completely custom connectortable.  remove the
the reverseddc option and try the following options.  We'll probably
have to sort out which dacs and ddc lines map to which ports.

go through these options and let me know which one works for you:

Option "ConnectorTable" "3,1,0,3,2,0,1,3"

Option "ConnectorTable" "3,0,0,3,2,1,1,3"

Option "ConnectorTable" "2,1,0,3,3,0,1,3"

Option "ConnectorTable" "2,0,0,3,3,1,1,3"
