Comment 27 for bug 307829

I'm not sure, Jason, but it seems difficult to include the amd74xx module. Look at the kernel changelog:

""linux (2.6.28-4.7) jaunty; urgency=low

  [ Tim Gardner ]

  * Build in most PATA/SATA drivers. This should allow most i386/amd64 systems to boot
    without an initramfs, though some support work is still required in initramfs-tools
    and grub.

pata_amd is not compiled as a module anymore, but build in.

I do not know what happened to this module (pata_amd) since 2.6.27 (in Intrepid) because works very well in hardy with 2.6.24.
