This is a very interesting find. Will this change to a custom class allow the driver to load in the native (bare-metal) case, too?
Also, Naty (Narcisa) has a patch for multi-BAR support, that we (Intel) were not able to successfully use...but it's working for her.
If you'd like to try it out, she can send it to you.
