Not a problem at all; the b43.blacklist=yes kernel param causes the
module to bail out; I used that to get 12.04 installed.
That said, I rebuilt to 11.10 to test older kernels, and that's where the
system is at the moment.
I've installed Ubuntu's b43 firmware package and rebooted into the
3.2.0-rc2 kernel.
that works, now.
