Even though ATI doesn't do XVMC, you still need at least XV or you will 
get 100% cpu usage. Better check that. That cpu should certainly be able 
to do 1080i, and probably will stay clocked low when displaying 720p.
If you're outputting via VGA or DVI, I found the "radeon" driver works 
fine; only used fglrx for TV out.
