I had mine working by largely following the instructions on this page:
http://www.kingcot.eclipse.co.uk/unichrome/unichromeTvOut.html

What I have in my xorg.conf is most importantly this:
Section "Monitor"
        Identifier  "TV"
        HorizSync    24.0 - 80.0
        VertRefresh  50.0 - 75.0
# Set for 4:3 display
#       DisplaySize     300 225
# Set for 16:9 display

        #Refresh Rate 60Hz

        ModeLine "848x480" 31.5 848 864 952 1056 480 481 484 497
        ModeLine "856x480" 31.7 856 872 960 1064 480 481 484 497

EndSection

Section "Device"
        Identifier      "VIA"
        Driver          "via"
        BusID           "PCI:1:0:0"
        Option          "DisableIRQ"
        Option          "EnableAGPDMA" "0"
        Option          "VBEModes" "true"   # Comment in for TV-out
#       Option          "AccelMethod" "exa"
EndSection

Section "Screen"
        Identifier "Default Screen"
        Device     "VIA"
        Monitor    "TV"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "720x576"
#               Modes    "720x576Noscale"
        EndSubSection
        SubSection "Display"
                Depth     16
                Modes    "720x576"
#               Modes    "720x576Noscale"
        EndSubSection
EndSection

Section "ServerFlags"
       Option  "AllowMouseOpenFail"
       Option  "AllowKeyboardOpenFail"
EndSection

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen          "Default Screen"
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"
EndSection

What I don't quite get is that the "720x576Noscale" mode is not working. I have
not defined it, and that probably accounts for it not working, but I see that
many others have it working, so I am at a bit of a loss about this.
