...might be appropriate.

That works when you know the intended _bus_ byte order, and bus
byteorder is always the same as the driver hardware byte-order. 

I don't see how it would work, in general, in chipset-level drivers,
for chips that appear on busses with different endian-ness.

Hey, that makes me happy, as long as the methods are wide enough to do
efficient access to bytestreams accessed via 16-bit, 32-bit or (even
64-bit) device registers.
