The mac mini needs a custom connector table like most other macs.
what connectors does it have? based on apple's web site, it looks like
it has just a DVI port that can drive DVI or VGA or tv-out (via DVI
adapters). I'm guessing it uses internal TMDS and the TV DAC. The
question is what ddc line it uses. Does adding the following option
in the device section of your config help?
Option "ConnectorTable" "X,1,0,3,0,1,2,6"
replace X with 1 or 2 or 3 or 4 or 5 until you get DDC working.
Once we sort this out, I'll add a MacModel option for the mini.
