One thing to add... I remember trying to run a diff over two dumps, and it turns out diff apps don't seem to be compatible with binary files 
So I imagine their probably are some programs that can do binary diffs, but I only saw some leads via Google. Good binary diffs could require some pretty heavy algorithms I suppose.
Anyway, I suggest trying to pin down numbers first. Like setting HP to a weird number (something big) and looking for every occurence of that number in the data segment that starts on a regular alignment boundary (Ie. not on an odd byte) ...and just hope most everything else is in that ballpark.
Btw, if you really feel daunted by the idea of handling dumps. You could still contribute by designing test map(s) that make it easy to test different variables I guess.
