Just an idea -- since this is bound to become an issue with more than
just the Coolscan2 backend, how about adding a "preference memory"
feature to xsane? You could save multiple sets of settings for the
same backend and recall them any time. This way you could set up one
for each type of film you are using. We could also add a flag to the
options in SANE2 that tells the front-end whether a particular option
is specific to the scanner as a whole or just the object to be
scanned: xsane would then have a way of saving exposure values but not
resolution and bit-depth, for example.
