But this is only for new bodies which recognise this.  Older bodies
will still spin the AF screw.  This will probably not be as noisy as
powering a lens from it, as the screw will be under minimal load.

This is sort of my point - the ability to take USM lenses is already
there and it wouldn't require any camera mods to work.  Of course it
would work *better* with a body designed specifically to do it, but
you'll still be able to stick your FA*USM lens on an LX, PZ, or MZ
body and have it work as well as that body can drive it.
