/* Some other twisted XFX board (rhbz#694914)
*
* The DVI/VGA encoder combo that's supposed to represent the
* DVI-I connector actually point at two different ones, and
* the HDMI connector ends up paired with the VGA instead.
*
* Connector table is missing anything for VGA at all, pointing it
* an invalid conntab entry 2 so we figure it out ourself.
