Yes, my code is running on the real hardware (I really would love to use
qemu, because of the much less development-time I would need to flash
the image aso. - but I don't have the time to analyze the problem).

I can see my code is running, the kernel boots, I see the LCD-mode of
480x640 @ 10 bpp is printed out on my serial interface and I can see
that the values inside the two loops are really saved into fbp (my
pointer to the probably fb-address).

I do not know what the next step could be, so the only answer (for me)
would be, the framebuffer needs to get an refresh signal or something
like that.
Also I am sure my hardware is not broken (I can run the original
openmoko-image / also I get normal output while u-boot is running).

Best regards,
Dennis
