The DRAC appears to report that it has a DVI port, but it only has a VGA port.
Attach a display to the VGA port and startup Xorg 6.9.0
With no xorg.conf file, Xorg.0.log says:

 (II) RADEON(0): Primary:
     Monitor   -- TMDS
     Connector -- DVI-I
     DAC Type  -- TVDAC/ExtDAC
     TMDS Type -- Internal
     DDC Type  -- DVI_DDC

and there is no sync signal.

Create an xorg.conf file, add the line:
If we put in  Option "MonitorLayout" "CRT, TMDS" it reports:

   (II) RADEON(0): Connector0: DDCType-2, DACType-1, TMDSType-0,
    ConnectorType-3
    (**) RADEON(0): MonitorLayout Option:
            Monitor1--Type CRT, Monitor2--Type TMDS
    ...

    (II) RADEON(0): End of Monitor1 EDID data --------------------
    (II) RADEON(0): Primary:
     Monitor   -- CRT
     Connector -- DVI-I
     DAC Type  -- TVDAC/ExtDAC
     TMDS Type -- Internal
     DDC Type  -- DVI_DDC


Now, the screen lights up. Notice that the report "Monitor" and "Connector"
above are contradictory.

On Xorg 6.8.2, the sync signal work fine, it does not need the MonitorLayout 
option. Even so, 6.8.2 reports "Monitor -- TMDS"
