As promised, I have looked at this with a fresh eye and NAK from me. Sorry.
This is less than a half baked solution. I spent couple of evenings, so
I'll come up with full conversion of this driver to the bitmap API.
And yes, as I have told you like half a year before, bitmap_get_value32() and
bitmap_set_value32() is much more useful (and I actually implemented them
locally for the sake of conversion).

So, summarize this I do not think we have real users of the proposed API.
