What if the user doesn't know the precise innards of their hardware. IDE
more than anything else has to automagically do the right thing. Given the
size of the PIO transfer loop and the way for some boards its weirdly 
dependant on hardware magic and wonder is there any reason for not just 
making the host controller provide the function or reference an ide library
function for "sane" hardware ?
