I have short circuited pins 2 and 3 of q6 on the personality board to
get power to the LCD. q6 is normally driven by the mc9s08 (pin ptf0). We
did not have any code for this chip at that time and then forgot about
it. As we now have a driver for it it should only be a matter of finding
the right bits to twiddle with. Patches welcome ;)

You can do a cp /dev/ram0 /dev/fb0 for some testing without the bmp
