Nah. OF doesn't know how to setup the TV Out I think and radeonfb
definitely doesn't. It's a quite complicated process, I've seen a bit
of code from ATI supposed to do that a while ago full of comments about
things not working properly & black magic =P

Maybe once I'll try again getting that to work but that mean that day
I'm really terminally bored :)
