Tested with all three applied and they work well on my TV all modes 
work, which was not the case previously if I added manually the modes 
listed in xorg log (I have three bogus/not working modes logged by xorg).

I do have a small problem with the interlaced modes - I assumed this was 
a radeon driver issue (the audio part obviously is - but the top line 
part is independent of audio)

I mention it just in case there is some link to the cae spec interlaced 
timings interpretation/implementation.
