I like this much better!

The lack of consistency with the config space access functions is a
bit of a pity, but your names are shorter, which is better in my
opinion.

I have one question though:

The 'fd' member here is specific to your Linux implementation.  For
OpenBSD I'll have to add other members.  How do we want to handle
that?

1. Just accept that there will be members that are unused on some
   platforms?

2. Add #ifdef's?

3. Move the definition of this struct into a platform-specific header file?

Anyway, I'll see if I can write the necessary support bits for OpenBSD.

Thanks,

Mark
