I just sent these to Christoph, but I recall him saying something
about being in transition right now, so I wanted to make sure these
patches ended up somplace safe for now.

Sorry this took so long, but I've been busy, and I had to migrate my
changes into your new upstream version. The diffs follow.
I had to modify configure.in in the scsidev directory, but I included
the diffs to the generated configure file, so you don't need to re-run
autoconf unless you just want to.
There are also some stylistic changes here (in debian/rules, etc.)
that you can feel free to ignore if you don't like them. I had to
change a few important things in debian/rules, though, so be careful
what you ignore.
The biggest change is to scsidev.c. There were potential buffer
overruns everywhere. I managed to eliminate many of them completely,
but for a couple I had to just make the buffer *really* large and hope
for the best because in those cases I couldn't find any documentation
for what the potential maximum size was.
Oh, and the patch looks bigger than it really is because I turned on
-Wall, and cleaned up all the resulting errors. This meant
rearranging the order of the functions so that they'd be defined
before use.
Let me know if you have any questions, and thanks...
