First off, I've never done anything this complicated, please be gentle.
Second, I know this will need to be broken up, but I'm not clear if
each commit should be able to compile. It seems having a commit for
each driver would make sense, but it won't compile cleanly without the
others. How do I go about that?
Third, this required a change to the kernel API(?) and I'm not sure
the best way to to make that change backwards compatible.
Forth, I'm getting an error on login. I don't think the kernel is even
trying the login. Maybe I can get a pointer to help me get this
resolved.
