[Centos] How to install 3ware Modules?

Hello all

I have compiled a driver 3w-9xxx.o for my centos 3.3 (Kernel 2.4 - grub). But now i have a problem. The 3ware controller and disks will be alone in the server. But that cannot work. So i have the following idea. I will install an IDE-Drive on the onboard controller. On that drive i will mount the boot partition. But now i must installed the modules in the kernel How can i do that? Or have you another good way to install the driver because the problem is that if the driver is not in the kernel the raid will not boot from them or?

I thank all who can help me.
