I'm in the process of staging a Dell poweredge 4300 as a new OES server.
During installation the Dell PERC2/SC raid card was not detected( it uses
the megaraid.ko module), I had to perform a manual installation. Which
enabled me to selectively load modules.

I've finished the installation, on reboot again the megaraid module is not
being loaded again. I notice that I have an initrd which includes the
megaraid module.

How do I force this module to be loaded at boot time. Is there any
parameter's I can pass to grub to have it loaded. Is recompiling the kernel
with megaraid built-in the only way of achieving this?
