I'm not actually using ATIs drivers at all IIRC - They wouldn't allow me to 
spec a TV supported res at all (That was sometime around Sept/Oct last year).

My device is:
01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 
PRO] (rev 01)
according to lspci.

I built my own, from these very instructions (I believe; or some looking very 
similar if not).

I spent a lot of time Googling (as you do in these situations), and I came 
across the configuration below (after many failed attempts), it isn't 
720x576, I found a 16:9 based res. I tweeked it slightly to make the screen 
more central (used some X modeline tool of which I can't remember the name).

Like I said that works fine for me, YMMV...
I believe the one commented out is the actual line I found out on the web 
somewhere (it may also have been my last working config though before the 
last change!).

Hope that helps...
