Benjamin Herrenschmidt 1f7b49d042 [PATCH] ppc32: add sound support for Mac Mini
This patch applies on top of my previous g5 related sound patches and adds
support for the Mac Mini to the PowerMac Alsa driver.

However, I haven't found any kind of HW support for volume control on this
machine.  If it exist, it's well hidden.  That means that you probably want
to make sure you use software with the ability to do soft volume control,
or use Alsa 0.9 pre-release with the softvol plugin.
