I've solved the problem now.
It turned out to be a very standard CRC algorithm, complicated
by the presence of a few extra bytes of data being checked that
didn't appear explicitly in the file anywhere.
In the process I developed some very general techniques for
solving this kind of problem, which I've written about here
if anyone's interested:

A good solution to an interesting problem - and very nicely explained too!
