That's even easier.

Add the disk driver names in modprobe.conf the ones for system disks  
in the top half, data disks below. Then run a mkinitrd.

Modprobe.conf excerpt:

alias scsi_adapter ata_piix
alias scsi_adapter0 ahci
alias scsi_adapter1 mega_sas
alias scsi_adapter2 mpt

# mv /boot/init-$(uname -r).img /boot/init-$(uname -r).img
# mkinitrd /boot/init-$(uname -r).img $(uname -r)

That should make an initrd with the drivers necessary to boot your  
other boxes (of course using your own disk drivers and not mine).
