Using libata for ICH5 PATA

["J.A. Magallón" <jamagallon@ono.com>]

Hi...

I want to try to use libata for my ide disks also.
Board is an ASUS PC-DL, it has an ICH5R controller:

00:1f.1 IDE interface: Intel Corporation 82801EB/ER (ICH5/ICH5R) IDE Controller (rev 02)
00:1f.2 IDE interface: Intel Corporation 82801EB (ICH5) SATA Controller (rev 02)

with 2 IDE100 busses and 2 sata ports,
and a Promise one:

03:04.0 RAID bus controller: Promise Technology, Inc. PDC20378 (FastTrak 378/SATA 378) (rev 02)

with one IDE133 bus and 2 sata ports.
More details here:
http://www.asus.com/products.aspx?l1=9&l2=39&l3=99&model=104&modelmenu=1

I boot from a SATA drive in ICH5, no initrd/initramfs, so SATA support for
ICH5 is compiled in.

I have now 2.6.17-mm1 installed, configured with:

CONFIG_IDE=m
CONFIG_BLK_DEV_IDE=m
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_PIIX=m
CONFIG_SCSI=y
CONFIG_SCSI_SATA=y
CONFIG_SCSI_PATA_OLDPIIX=m
CONFIG_SCSI_ATA_PIIX=y
CONFIG_SCSI_SATA_PROMISE=m

The ata_piix does not show the PATA bus.

libata version 1.30 loaded.

If I modprobe sata_promise, it works as I expected:

Finds both SATAs and the PATA.

This is what the 'old way' with piix gives:

What do I need to let libata drive the ICH5 pata ?

TIA
