the system does not have a serial port.
maybe there is one on the MB ... however it is not wired to the case.

I changed the "options" line to modeset=0 (was modeset=1) without any
success
Also tried nomodeset at the grub kernel-bootline,
no success either
the kernel unfortunately dosen't have /proc/config.gz enabled, so I
could not check if CONSOLE_FB is enabled.
maybe I have to bake my own kernel ...
