Nice.

Output on one of my machines is however not as expected:

Controller device @ pci0000:00/0000:00:1c.1/0000:02:00.0 [ahci]
   SATA controller: JMicron Technology Corp. JMB360 AHCI Controller (rev 02)
     host4: [Empty]

This machine has seven SATA ports: one provided by the JMicron chip, the 
other six by the Intel H55 south bridge. Only three ports are currently 
used, but I had expected another [Empty] entry.

Here's what's in /sys/devices:

root@zotac:~# find /sys/devices/ -name scsi_host
/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/host4/scsi_host
/sys/devices/pci0000:00/0000:00:1f.2/host0/scsi_host
/sys/devices/pci0000:00/0000:00:1f.2/host1/scsi_host
/sys/devices/pci0000:00/0000:00:1f.5/host2/scsi_host
/sys/devices/pci0000:00/0000:00:1f.5/host3/scsi_host

Not sure what to make of that...
