Here are some more informations. There seems to be a scaling problem.
If i compare gma500 and the vesa framebuffer driver I see that gma500 shows
the desktop "scaled" up --> not the whole desktop is on the screen. It
gets better
if i remove the video="..." parameter from kernel cmdline, but it
still is too big for
the screen.

I really would love to get this beast up an running... so I will
provide as much informations
as needed - just ask :)
