Right. That's why we designed it the way that we did.
Unfortunately, as with anything that attempts to generalize hardware,
it has warts. I'm sure that there are some bus bridges out there
somewhere that byte-swap in hardware for particular address ranges,
for instance, and those will be annoying to deal with...
However, you have to make _some_ assumptions in order to make drivers
