I have a system that has a 4bpp monochrome display and the driver doesn't 
work. After initializing, it turns on the display[1] but I fail to get any 
content onto it. I extended the array with the display characteristics 
according to an existing driver, but to no avail.

I'm pretty lost there, since I have zero prior experience with framebuffers or 
video drivers, so I'd appreciate any hint that might get me towards debugging
