I received a code snippet from Michael Schmitz, but NetBSD has an
M.I. IDE driver, so register base address and interrupt were pretty
much all I wanted to know.  I'm trying to integrate the M.I. wdc
driver into mac68k modeling other archs (i386, alpha, and atari).
What I have to do right now basically is understand kernel config file
syntax, semantics, and structure, which has proven to be a little (ok,
much ;-) harder than I thought would be.

At any rate, coorperation between the two camps is much better than no
coorperation.
