Krzysztof: given this, I think it would be fair to add an enum to the 
driver to keep track of the actual hardware type (grouped into probably 
just 3, S3C24XX, S3C6400, APPLE), get rid of any code in there that 
cares about the uapi-visible port type (other than setting it correctly 
for those that do exist, to maintain current behavior), and just make 
everything else use PORT_8250 for that?
