If you are sure that the one who who is the copyright holder of the
original code isn't against GPLing the code, you can put the GPL into
each of your files. However, I won't include it in CVS without
clarification from the orginal authors. Maybe one of the other SANE
developers feels otherwise and committs them to CVS.

The latest scanner drivers can send control messages, this stuff is
even in sanei_usb (see
http://sanei.meier-geinitz.de/sanei__usb_8h.html#a7).

I don't know what about the other changes.
