CentOS - Dec 2008 - C5: prevent loading of AHCI in favor of "fakeraid" megaide

Hi,

I'm trying to install an old fujitsu siemens econel 50 server.
It uses an Intel chipset with ICH6R sata subsystem known as fakeraid.

I have configured a Raid 1 with two 160GB hds.

FS and Intel both provide a driver called megaide on a driver disk to 
use fakeraid and here is the problem:

- The readme tells me to install with the "nostorage" kernel option
and
I can load the megaide driver with the driver disk.

- in anaconda I only see one disk sda - exactly what I want.

- after installation when booting the 92.el5 kernel obviously the ahci 
driver is used not the megaide, LVM complains about identical PVs on sda 
and sdb and I can unload megaide while running the server

- so megaide is not used upon reboot but ahci

- megaide is inside the initrd but - probably because ahci loads first - 
    not used

Question:
How can I prevent the ahci driver to load after installation?

Thx
Rainer

PS: I know the pros and cons of fakeraid - I want to use it. Plz no 
discussion about this.

Try adding 'blacklist ahci' to /etc/modprobe.d/blacklist

Also check for and comment out any aliases to ahci in /etc/modprobe.conf
