[CentOS] Module loading order during install

Is there a way in a kickstart install to affect the order in which modules 
get loaded?  I want to load 3w-xxxx before 3w-9xxx so that my OS mirror 
drives take their proper place as sda and sdb, but centos-4 wants to load 
3x-9xxx first, making my (unbootable) big arrays the first two drives.  In 
this configuration, it seems that even trying to install grub to /dev/sdc 
fails.  Ideas?  Thanks.
