Ah, that would explain it.  VGA uses a DAC, DVI uses a TMDS
controller: different hardware.  Since apples have no connector table
we hardcode the connectors.  by default I set up LVDS and VGA.  I
suppose since we know all the apple models so we can be more specific
based on pci subsystem ids or something.  The question is, does your
laptop use the internal TMDS or external?  If it uses internal, we are
all set, if it's external, you'll have to init the external chip using
macos first as we do not currently have code in the driver to do it
yet.  Benh might know.  Anyway, here's how to test:

Add one of the following to the device section of your config:

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

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