This is what I would prefer and is what the first version of this patch
that I submitted a year ago did: http://landley.net/qemu/2008-01-01.html
The problem is that every hardware driver would need to be changed and
some of them would need to be changed drastically because they use the
same functions for all three data sizes. No one seemed interested in this
approach so I abandoned it.
This approach while uglier requires no changes to the hardware drivers
unless they need 64 bit support so I hoped it would be better received.
