What that means is that the manufacturer does not provide software for anything other than XP and Vista. It does not mean that the scanner will, or will not, work with other systems if you get suitable software from somewhere else.

Have you tried looking at the hardware compatibility list? This should probably be your first or second port of call (after SANE, maybe).
