This has been discussed later in the thread, but I figured I'll answer
too:

Without a second SATA drive, I can't verify for sure. But the
"io-device-location" property in ../k2-sata@0/io-device-location is "A
(upper)", and for ../k2-sata@1/io-device-location it's "B (lower)".
There's only two drive locations on a G5, so that corresponds to the
physical locations of the two drives.

As previously mentioned, there's only one drive per bus on SATA, so it
makes sense logically as well (k2-sata@<busno>/disk@0).

If someone else has more hardware and can test; please do and let us know
if this is correct. Otherwise, It'll have to wait until I order another
drive (WD Raptor anyone? :).
