I've got 

  00:1f.1 IDE interface: Intel Corp. 82801AA IDE (rev 02)

so it looks like you have a newer version.  The AA works fine; I'm
running 2.4.19.

  ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
  ICH: IDE controller on PCI bus 00 dev f9
  ICH: chipset revision 2
  ICH: not 100% native mode: will probe irqs later
      ide0: BM-DMA at 0x1800-0x1807, BIOS settings: hda:DMA, hdb:pio
      ide1: BM-DMA at 0x1808-0x180f, BIOS settings: hdc:DMA, hdd:pio
  hda: WDC WD600BB-00CAA0, ATA DISK drive
  hdc: CD-RW BCE2410IM, ATAPI CD/DVD-ROM drive
  ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
  ide1 at 0x170-0x177,0x376 on irq 15
  hda: 117231408 sectors (60022 MB) w/2048KiB Cache, CHS=40079/225/13, UDMA(66)

The PIIX supprt is for Intel 82801XX stuff.

If you've never compiled a kernel before; never fear ... just install
'kernel-package', 'fakeroot', and either install a kernel-source
package or grab kernel source from kernel.org.  We're here to help :)
