Oh, no!  I sent the wrong patch!

While I was testing it, I tried to make sure that if I claimed that my 
processor could understand MVI, it would try to compile it.  I forgot to 
change it back before sending it.  The patch that I sent will work on 
everything BUT the ev56.

Attached is the proper one.  Sorry.
