this instance of the driver is getting the DVI port.

ati is just a wrapper.  it loads radeon or r128 or mach64 depending on
what chip you have, so it doesn't matter which one you have.

In your case, since you system has LVDS, DVI, and VGA, it's ending up
with DVI and VGA for each zaphod head.  You'll have to force the
connector table to get this to work.  If you want to use LVDS and VGA,
add this option to each device section:

Option "ConnectorTable" "0,0,0,7,96,1,0,1"
