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.
