This large patch adds all of snd-aoa. Consisting of many modules, it currently replaces snd-powermac for all layout-id based machines and handles many more (for example new powerbooks and powermacs with digital output that previously couldn't be used at all). It also has support for all layout-IDs that Apple has (judging from their Info.plist file) but not all are tested. The driver currently has 2 known regressions over snd-powermac: * it doesn't handle powermac 7,2 and 7,3 * it doesn't have a DRC control on snapper-based machines I will fix those during the 2.6.18 development cycle.
