there should be page-height and page-width options, which defaults to
US letter. the adf needs to know how big the paper is so it can center
the width and detect multi-feed via length. the scan area is then
clamped to the page size. I guess on the flatbed these are kind of
useless.

i dont know anything about mac specific frontends. can you use one
that works with sane directly like xsane or xscanimage instead of all
this sane to twain stuff? what you are looking for is a 'Source'
option

most definitely. set the source to "ADF Duplex". also requires that
your frontend keep asking for pages repeatedly.
