The one instance I had to version something big (50MB iso image), I ran
md5sum on the image, and committed that output. (md5sum, if you aren't
familiar with it, is a program to print or check 128 bit checksums. It's
output is 1 line of text). The make process that uses the image is
responsible for verifying the md5sum at the time it uses it.

This does have some serious disadvantages, and makes it VERY hard to deal
with large files that change frequently (mine won't), but otherwise it's a
useful technique.
