Lots of little fixes. We no longer panic on card insert:
o initialize ivars with bzero.
o remove interrupt function pointer. netbsd needs it, but we don't.
o add lots of comments about bogus things that I've been kludging to try
to make the simple cases work.
o add new ivar accessor for cis4 to match cis3. likely neither will be
needed, but it doesn't hurt to have it.
