Denis,

Going back in  the myth-users archives I found a post from me a while ago
where I posted my entire xorg.conf.  This was my configuration using a
regular CRT Tube RCA television with an Nvidia card.  Of course you'll have
to modify the driver options to suit your ATI card:

Section "Module"
    Load        "dbe"  	

    SubSection  "extmod"
    EndSubSection

    Load        "type1"
    Load        "freetype"
    Load        "glx"
EndSection

Section "Files"
    RgbPath	"/usr/X11R6/lib/X11/rgb"
    FontPath   "/usr/X11R6/lib/X11/fonts/local/"
    FontPath   "/usr/X11R6/lib/X11/fonts/misc/"
    FontPath   "/usr/X11R6/lib/X11/fonts/75dpi/:unscaled"
    FontPath   "/usr/X11R6/lib/X11/fonts/100dpi/:unscaled"
    FontPath   "/usr/X11R6/lib/X11/fonts/Type1/"
    FontPath   "/usr/X11R6/lib/X11/fonts/CID/"
    FontPath   "/usr/X11R6/lib/X11/fonts/Speedo/"
    FontPath   "/usr/X11R6/lib/X11/fonts/75dpi/"
    FontPath   "/usr/X11R6/lib/X11/fonts/100dpi/"

EndSection

There might be a slight difference in the way that I ran my distro, I
didn't use a login manager such as GDM or KDM when booting into X.

Most of the time when I needed to switch over to the TV-Output I would
change the "Screen" directive under "ServerLayout" to "TV"
instead of "LCD" and restart the X Server.

Hope this helps.
