You have two completely orthogonal problems:

 1) changing b43 so it knows how to talk not just to SSB/PCI/PCMCIA
    chips but also SDIO chips

We already have working support for that and we're currently merging it mainline.
If you want to help, please test the spinlock removal patchset I just posted.

 2) changing b43 so it knows how to talk to your specific radio/PHY
    chip, and LP PHY

Also almost working and in the progress of merging mainline.

Greetings, Michael.

Okay, I'll first look into it, and then do some tests.
Thanks.
