Last step of the kernel rpm install script is to generate an initrd  
file, so as long as your scsi_adapter order in your modprobe.conf is  
right your initrds should be right.

If you need a special adapter loaded before the SCSI adapters then  
there are preload options that can be set in /etc/sysconfig/initrd.
