I dare to differ.

IIRC  `modprobe ata_piix` generates logging in /var/log/syslog
with information about the chipset (disc-controller) found.

So there is the clue for succesfull `modprobe ata_piix`

I agree on the fix in pci.lst.

I'm not sure about the "kernel module must properly handle hardware".
IMNSHO are inserting kernel modules and scanning for discs
two _different_ actions.


My questions:

* What is the _right way_ to scan for disks in debian-installer?
 * How to trigger it?  (which menu item?)
 * How to check the result? (which command in the vt2 console?)
