ah! now that makes sense.
So, I'm guessing the DS register is used by default to select the base address for all non-stack oriented operations. And I bet the SS register is used by default for stack oriented operations, and all ops that act on %esp (and %ebp?). I think that make my life easier.
Thanks a lot!
