The kernel patch I used for the machine I had can be found in bug
1066435.  Until the patch(s) make there way into the kernel, I suggest
people use DKMS to compile the snd-aoa modules, rather than recompiling
the whole kernel.  Of course you may have to adapt it for your machine.
Submit your patch to the linuxppc/alsa devel lists and then raise an SRU
on the ubuntu kernel.

Title:
  [PATCH] Fix sound on PowerPC

Status in “hw-detect” package in Ubuntu:
  New

Bug description:
  This patch is one of several needed to fix sound on PowerPC.  The
  wrong modules are loaded/blacklisted on many machines, causing sound
  not to work or worse the fatal "Fixing recursive fault rebooted is
  needed!" bug -
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1066435

  The attached patch incorporates the suggestions in this debian bug
  report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=650588 , and
  additionally splits off the 'i2s-a' machines which nolonger use
  snd_powermac (at least that is what I understand from this linuxppc-
  dev message -
  http://comments.gmane.org/gmane.linux.ports.ppc.embedded/51204 ).

  It would be excellent if this could make it into Trusty.  I'm going to
  submit another bug on the casper package.
