load detection on the TV DAC is a bit unreliable and since the DAC is
shared between tv-out and VGA, you often get false positives on one or
the other connector depending on what's attached.  I'll probably add a
driver option to force enable load detection on the TV DAC so you can
enable it at server start.  If you want to enable it by default now,
you'll need edit radeon_output.c as follows:

change line 1782 (radeon_create_resources()) from:
data = 0;
to:
data = 1;
