The load detection code for tv-out is a bit flakey on some chips.  Can you try
commenting out lines 1413 and 1414 of radeon_output.c and see if that helps? 
remove these lines:

     if (IS_R300_VARIANT)
         return r300_detect_tv(pScrn);

If not I may just disable tv-load detection by default.
