Thanks, this was very helpful advice (to be explicit, i needed
linux-headers-2.6.32-5-powerpc, not linux-headers-2.6.32-5-amd64, and i
built it as a non-privileged user after unpacking
/usr/src/linux-source-2.6.32.tar.bz2 into the user's home directory,
varying the M= argument above to match).
So as the superuser, i replaced
/lib/modules/2.6.32-5-powerpc/kernel/sound/ppc/snd-powermac.ko with the
hand-built snd-powermac.ko, and ran depmod -a.
i can do:
modprobe -v -r snd-powermac
modprobe -v snd-powermac
and my audio still works with the new module. so that's good!
But it still doesn't get auto-loaded for me.
i made sure snd-powermac was not listed in /etc/modules, i re-built the
initramfs, and i re-started the system.
It came up without snd-powermac.ko loaded, and i had to load it by hand
again.
I can tell that i've got the hand-built module in /lib/modules instead
of the original:

So what am i missing? Is this sufficient info, but now udev needs to do
something else? or is there some other patch that needs applying?
I note that the following snd modules *are* auto-loaded -- i don't know
if this is useful info or not:
