So, you need modprobe.conf to reflect this as well as a new initrd.
On a similar system I have from Asus my modprobe.conf looks like this:

alias scsi_hostadapter ata_piix
alias scsi_hostadapter1 ahci

I assume the ata_piix is still required for the jmicron ide controller.
After editing this, run mkinitrd which will look there and then load the
required modules.
