I was able to successfully build this module in kernel 3.8.0-27 per
comment 29
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1173761/comments/29
on 3.11.0-031100rc3-generic).

        $ sudo dkms build -m b43b1 -v 6.30.223.95

        Kernel preparation unnecessary for this kernel.  Skipping...

        Building module:
        cleaning build area....
        make KERNELRELEASE=3.8.0-27-generic....
        cleaning build area....

        DKMS: build completed.

However, I could not remove the existing wl module (using "sudo rmmod
wl") because Ubuntu/Linux kept insisting that the wl module was in use.
(This was the case even if I disabled wreless from the BIOS).  I even
tried "sudo rmmod --force wl", but it did not work.  Nevertheless, I
proceeded to install the new module and it worked after a reboot.

However, I want to point out that this also actually fixed a different
bug in 3.8.0-27!  I was unable to shutdown or restart the machine.  It
would just hang during the shutdown process.  This is the bug:
https://bugs.launchpad.net/ubuntu/+bug/1176028.  After installing
hybrid-v35_64-nodebug-pcoem-6_30_223_95, my computer shutdowns and
restarts normally.  I am mentioning this because the wireless fix (or
something included in the fix) may be related to bug 1176028.

Just to confirm everything is workign smoothly, I did a fresh install of
13.04, updated all packages, and then aplied  hybrid-v35_64-nodebug-
pcoem-6_30_223_95.  Both bugs #1173761 and #1176028 seem to be fixed.

I could only test Wireless 802.11n, since I do not have a 802.1ac
network.  Also, I can not verify if the 5Ghz or the 2.4GHz band is being
utilized.  Finally, Bluetooth, included with the Broadcom 43b1 device,
still does not work.

Title:
  14e4:43b1 Broadcom Corporation Device 43b1 (rev 03) - not supported

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Both during and after installation, 13.04 doesn't support the
  Broadcom-based 802.11ac wifi chipsets.  lspci reports it as "Network
  controller: Broadcom Corporation Device 43b1 (rev 03)".

  Would love to see this worker as it's being a bit of a show stopper for me.
