Just to make it entirely clear I am connecting the TV directly using a
DVI cable (no switch).

I will triple check this evening to make sure this is indeed what's
happening but i'm fairly confident.

It's interesting to note that:

1) If the DVI cable is not connected then the mac mini refuses to boot.
2) If the DVI cable is connected and the TV is on standby then the mac
mini boots but the Intel driver considers the TMDS-1 interface to be
disconected.
3) If the DVI cable is connected and the TV in powered up then everything works.

The difference between (1) and (2) indicates that there is a
difference to the device presence detection being performed the mac
mini at powerup and the Intel driver.
