We do load detection on the tvdac for tv-out detection, however, it's not
always reliable on all different chips, hence you get false positives on
occasion.  There is an alternate tv detection routine that seems to work better
on some r3xx chips.  you can try it by commenting out lines 1414-1414 in
radeon_output.c

remove these:
     if (IS_R300_VARIANT)
         return r300_detect_tv(pScrn);

We may just have to turn off load detection by default for the tvdac.
