Alignment _might_ be different, though I think it isn't actually as long
as we're talking about x86_64 (amd64) only.

If the driver uses wireless extensions (likely), it might have issues
with that too, since they are not very 32/64-bit compat happy (unless
you're using 64-bit userspace exclusively obviously)

I can't think of anything else right now.
