Spot on. After switching the BIOS to AHCI mode, output now looks like this:

Controller device @ pci0000:00/0000:00:1c.1/0000:02:00.0 [ahci]
   SATA controller: JMicron Technology Corp. JMB360 AHCI Controller (rev 02)
     host6: [Empty]
Controller device @ pci0000:00/0000:00:1f.2 [ahci]
   SATA controller: Intel Corporation 5 Series/3400 Series Chipset 6 
port SATA AHCI Controller (rev 06)
     host0: /dev/sda ATA WDC WD20EADS-00R {SN: WD-WCAVY4080404}
     host1: /dev/sdb ATA ST3500418AS {SN: 9VMK33L9}
     host2: [Empty]
     host3: /dev/sdc ATA ST3500418AS {SN: 9VMM6EY4}
     host4: [Empty]
     host5: [Empty]

So the south bridge is now seen as the single chip that it is, instead 
of two emulated-ones. It is now also controlled by the ahci driver. And 
all of the unused ports are there.

Great stuff, thanks.
