Yes. These are my settings from xorg.conf (short summary):
...
Section "Device"
    Identifier    "S3 UniChrome (CN400) TV"
    Driver        "via"
    BusID        "PCI:1:0:0"
    Option         "ActiveDevice"         "TV"
    Option        "TVType"        "PAL"
    Option        "TVOutput"        "S-Video"
    Option        "EnableAGPDMA"        "1"
EndSection
...
Section "Monitor"
    Identifier    "TV PAL"
    VendorName    "Thomson"
    ModelName    "28DN420E"
        Option          "nodpms"
        Option          "noddc"
EndSection
...
Section "Screen"
    Identifier    "Screen1"
    Device        "S3 UniChrome (CN400) TV"
    Monitor        "TV PAL"
    DefaultDepth    24
    SubSection "Display"
        Depth        24
        Modes        "720x576Over"
    EndSubSection
EndSection
...

By inspecting the xorg.0.log those modes -> 720x576Over, 800x600Over, 
720x576Noscale, 640x480 are available (like I said already).
Not "1024x768Over" :-( But according to "$ man via" it should be.

Another observation when I try to use "1024x768Over":
Log-->
...
(II) VIA(0): TV standard is PAL. This is a NTSC mode.
(II) VIA(0): Mode "1024x768Over" not supported by TV encoder.
(II) VIA(0): Not using default mode "1024x768Over" (unknown reason)
(II) VIA(0): Not using default mode "1024x768Over" (hsync out of range)
(II) VIA(0): TV standard is PAL. This is a NTSC mode.
...

Then I've made a test. I switched everything over to NTSC in order to 
see if "1024x768Over" is available.
Surprise. It's not

Option "TVNorm" "PAL" --> xorg.0.log says it's a NTSC mode
Option "TVNorm" "NTSC" --> xorg.0.log says it's a PAL mode

hmmm?? Is there a bug in retrieving the correct video mode or am I just 
wrong???

BTW: I forgot to mention my bios version. It's v1.07
