Sorry, I have no upload place to put some screenshots. 

The natural resolution of the display is 1280x800 pixel.

When existing to the loader and issuing as recommended the command "gop list", I get
three modes:

mode 0: 1024x768x32, stride=1024
mode 1: 640x480x32, stride=640
mode 2: 800x600x32, stride=800

Setting mode 1 and 2 via gop set X solves the problem and the screen is, at least during
a live session of the latest 12-PRE USB image, readable and looking normal.

As soon as I have an installation media, I'll check whether the screen is operable after
installation (and, of course, loader settings as required), or not.

Thanks for the quick help!

Kind regards,

O. Hartmann
