Arnd, right now I'm loosing a lot of time (I could spent on improving
bcma or b43) on posting new version of this huge patch with single
changes. Changes that can easily be introduced later without breaking
driver, ABI, etc.

I'll be glad to try your solution later, when we get this patch
merged. I'll be much easier to play with such a differences then.
Thanks for sharing this idea.

Right now I want to focus on some bugs in driver that don't allow it
being merged.
