Nobody knows what these bu^wlimitations will be though. So you cannot
really plan for them in advance. When someone writes drivers for such
limited hardware they can add code to handle the limitations. But it
seems reasonable to start with a clean hardware model, and only
add the hacks later when they are really needed and the requirements
are understood.
