B43 N mode

Hello, I am using a BCM43217. And I'm wondering if there are any B43 devices which work in N mode?

I guess my main question is, is there any reverse engineering tools that work with a Broadcom MIPS router. Mostly to monitor the PCI bus. Which 'hopefully' I can add to the GPL source which is supplied by large companies.

The tool I used on x86 / x86_64 is mmiotrace. It's not available for MIPS.

Rafa?

Thanks for responding. Perhaps I will try to hard-code some addresses and transfer the data between them?
