The __devinitdata solves this.

The problem here is that emac_probe calls zmii_detach. emacs_probe is a 
__devinit and zmii_detach is a __devexit. At least I assume that is the 
problem.

I am a long time emacs (actually xemacs) user. If I had a nickel for 
every time I typed emacs rather than emac, I would be a very rich man.
