There are 2 SATA controllers, so 4 ports, inside of K2 but apple only wired 2 of them in the current G5s (I think the Xserve use all of them or at least 3). The sound bus isn't visible on PCI, it's inside K2/KeyLargo (along with some other things) which provides i2s & i2c busses. Like all older macs. There are some subtle differences though since the G5 has 2 sounds chip on those busse (an analog an a digital, one of them just beeing a tas 3004). All of the details can be found in the darwin drivers, they are open source. Ben.
