Ok, thanks for the prompt reply and the notice for the cc: :)
I'm using libata and ata_piix now.
My disk is seen as "sda" and a lshw is reporting the controler as using "ata_piix" :

# lshw -c STORAGE
   *-ide
        description: IDE interface
        product: 82371AB/EB/MB PIIX4 IDE
        vendor: Intel Corporation
        physical id: 7.1
        bus info: pci@0000:00:07.1
        logical name: scsi0
        logical name: scsi1
        version: 01
        width: 32 bits
        clock: 33MHz
        capabilities: ide bus_master emulated
        configuration: driver=ata_piix latency=0

But fdisk always recognize the disk as 136.8Gb :

# fdisk -l

Disk /dev/sda: 136.8 GB, 136899993600 bytes
16 heads, 63 sectors/track, 265260 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Disk identifier: 0xd7267427

    Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1         204      102815+  83  Linux
/dev/sda2             205        2236     1024128   82  Linux swap / Solaris
/dev/sda3            2237       20805     9358776   83  Linux

Here is the new kernel config file : http://pastebin.com/f65fd472b

I would definitely be interested in seeing the 'dmesg' output for libata, and results from a more recent kernel.
