Hi,

thanks a lot for that, X works now. I couldn't get any of the modelines in
XF86Config to work though and had to use

...

Section "Screen"
    Driver      "FBDev"
    Device      "Linux Frame Buffer Device"
    Monitor     "LCD Panel"
    DefaultColorDepth 8
    SubSection "Display"
        Depth       32
        Modes       "default"
    EndSubSection
EndSection

The Xserver seems to be rather slow. Is that expected?

I also tried 

Mode "1024x768"
    # D: 64.994 MHz, H: 48.359 kHz, V: 59.998 Hz
    DotClock 64.995
    HTimings 1024 1085 1221 1344
    VTimings 768 771 777 806
    Flags    "-HSync" "-VSync"
EndMode

but that lead to a complete freeze, kernel and all. I got this from 
"fbset -x". It looks like a sensible modeline for the StudioDisplay Flat
Panel Display we have. 

Cheers, Stefan
