Comment 9 for bug 476154

Blindly assuming the changes for b43 just can be taken to b43legacy, I build some test kernels on that base. They can be found at http://people.canonical.com/~smb/bug476154/ as well (the -16 kernels).
@tournesolo, can you check whether this solves your problem? If yes, I assume the other bug you mentioned (bug 450159) is for the legacy version of the b43. So this should then be followed up the other report (as well as here) and then I see to send the patch upstream and to stable.
