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.
