I have had a similar problem on box of mine trying to get DMA working on 
my DVD player.  The solution was to change the order of the modules in 
the initrd.

On my box (which is CentOS-4 with Custom FC4 kernel) I put this in 
alias scsi_hostadapter ata_piix

and then rebuilt initrd with mkinitrd.

and added
to the kernel in grub.conf

That might help.
