I've tried that too. I've created a modeline now with

Section Monitor
        Identifier      "TV"
        Option          "DPMS"
        Mode            "1280x768"
                        DotClock        81
                        HTimings        1280 1368 1440 1688
                        VTimings        768 769 772 800
        EndMode
        ModeLine        "1280x768"       80.14   1280 1368 1440 1688   768 769 772 800
EndSection

and all i get is a 640x480 resolution and the warning

(II) I810(0): Not using mode "1280x768" (no mode of this name)

I even tried this with a special modes section and a UseModes, but it
still ignores the modelines. Googling around brings up many sites and
all advice, to use 915resolution (which i did, mode 5c is patched to
1280x768) Any ideas?

Thanks in advance,

Christoph
