Hewlett Packard used to give developers a free Twain-compatible scanning
library for 16-bit DOS.  All I had to do was answer a 5-minute
over-the-phone questionnaire.  I don't know if they now offer a 32-bit
version, or even if they still offer it at all.

Twain is an interface standard and does not require Windows.  All that's
required is a Twain-compatible device driver and library.

Of course, though different approaches are possible for different video
modes.  You have to decide which approach you want: hardware split
screen with mode-x, software control through overlapping bitmaps with
software scrolling, software control through stretching bitmaps to fit
the given screen, etc.
