I've done a diff against 2.6.31, but there are too many differences, so I can't easily tell what they have added and what was changed in the development between 2.6.21 and 2.6.31.
One thing is clear: They added several "case" instructions with code for the MPX-885. So I guess, they really got it working. I'm downloading kernel 2.6.21 now and make a diff with these drivers.
