well, it does, at least for some versions of the 2480. Some people 
have reported problems similar to yours (see, e.g. 
http://alioth.debian.org/tracker/index.php?func=detail&aid=301010&group_id=30186&atid=410366 ).
For others, the scanner seems to work perfectly (mostly using 
sane-backends 1.0.15).
I have no clue why this problem occurs for some users and not for 
others. As far as I know there is no correspondence to any version of 
the backend. In fact the code for scanning transparencies has hardly 
been changed in the last three years. I doubt that an earlier version 
of the backend will solve your problem.

As I explained in another mail the reduced scanning area in 
transparency mode is a security measure for 2580 users.

There is always a third possibility: Fix the problem.
