Let me address this, now... say I have an NE2000 in a 533MHz Alpha (quite
plausible, although stupid :-) ... even though I'm not overclocking the
hardware, I could still run into this problem simply because the countdown
loop would expire too quickly.

If a comment in a piece of code says "wait 5ms", the code should take some
measures to make sure it waits at least that long.
