Ah, that explains a few things. TV load detection probably fails because in VGA
mode the TV encoder lines aren't even electrically connected to the mini-VGA
port.
Most likely there's a GPIO-controlled switch you have to poke to make TV-out
work: the attached patch is just a wild guess, if it has no effect you could
try to play a bit with the "gpio->line" parameter (values in 7-9 and 2-4 should
be safe).
BTW, do you happen to have access to one of these adapters?
