I don't care what bus the device is on, just its address, and code  
exists to access the device that way.
I see no reason to simulate an instruction from another architecture  
(inb/outb).
If the 16550 was on the system without an ISA then inb/outb would be  
useless.
I'm proposing we use readb/writeb exclusively.
