Its great to hear that you have it working!

I've been so buried under work trying to get away for a week's
vacation that I haven't had a chance to look at *any* of the ColdFire
stuff for the month of July.  When you get a complete patch together
against my tree(@baradas.org), send me a mail, I'll integrate it, and
then start adding my v4 changes to it...

I'm still looking into the ColdFire reload problem(attempt to load a
QImode value from memory into an address register), but without much
success.  I think I have to learn a *lot* more about reload before I
can understand where its going wrong.
