Hello,

Regarding the Mac mini, I'm curious about something. Apple says that there 
is only one ATA bus:

http://developer.apple.com/documentation/Hardware/Developer_Notes/Macintosh_CPUs-G4/MacMiniG4/index.html

But in Matt Thomas' mini dmesg, there seems to be two busses:

wdc0 at obio0 offset 0x20000 irq 24: DMA transfer
atabus0 at wdc0 channel 0
...
wdc1 at pci2 dev 13 function 0: interrupting at irq 39
atabus1 at wdc1 channel 0

So the first bus, like the two extra non-fast USB busses, is just unused, 
right?
