No he isn't and that's why I'm rude -- everything needs to be repeated over and over and over again. Read the thread(s). You didn't limit your reply to chipset logic and Alan even already submitted patches to isolate the delay for the chipset logic (PIC and PIT that is) where the expectation is that a simple udelay() will suffice. We've already talked about ISA bus speed, and how it's not in a sane sense portably determinable, we've already talked about kernel parameters, about udelay and it's usefulness in early boot, about how your rude "Junk I/O" is exactly what is needed for some ISA devices and so on... In fact, we're blue in the face from talking about it. So say something useful or go away.
