radeon 9250 t.v support?

[mandriva_boy]

i have a radeon 9250, and it works fine (now) i use the Radeon (fglrx) drivers on the mandrive 2005 system, and i wondred, is there ANY way to get X.org to recongnise the t.v out on the card and use it as another moniter? also, GLEST freezes X on my system, i think it's because i need to underclock (yep UNDERclock) my AGP subsystem.. any ideas on the sis 730??
