Not sure, but we will find out :)

Depends on if I can find it.  A lot of this older documentation I have
not been able to locate *sigh*.  I have not spent much time looking for
it yet, because I have not started on the drivers yet.  The only driver
I have started on was the MUX driver, and I was unable to locate
documenation so far, but I have not given up yet.

I have a bunch of cards, so pick one that you want to work on, and I can
start on a different one.  I've been working on the MUX lately, but with
your PDC patch, I'm kinda leaning towards the skunk or wizard scsi
card.  I have a stack of cards that to work on, so feel free to grab the
one that suits your fancy :)
