I have seen that before on one of my computers:

  atapci0: <VIA 6420 SATA150 controller> port 0xd000-0xd007,0xcc00-0xcc03,0=
xc800-0xc807,0xc400-0xc403,0xc000-0xc00f,0xb800-0xb8ff irq 20 at device 15.=
0 on pci0
  ata2: <ATA channel 0> on atapci0
  ata3: <ATA channel 1> on atapci0
  atapci1: <VIA 8237 UDMA133 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177=
,0x376,0xfc00-0xfc0f at device 15.1 on pci0
  ata0: <ATA channel 0> on atapci1
  ata1: <ATA channel 1> on atapci1

It looks like ata0 and ata1 are assigned to whichever interface looks like
the "standard" ATA interface, regardless of in what order various ATA
controllers are detected.
