Jon,

This may not be the most elegant way, but try puting tests to see if
the macros have already been defined around the include directive, so
that it only includes io.h if they have not.  This kind of trick is
all over the EMC source for various reasons so you should be able to
find a model.

Also, the file to include has changed sometime between the 2.0.x
kernels and the present.

You might look at some of the multi-source-file drivers like smdromot
(or is it smdromod at that point?)  I don't have the code here at work
but could look at it later if someone else doesn't clear things up
first.

Chris
