You have a choice: You can either include a "initrd" that has the
relevant modules, or use "bultin" rather than modules (i.e. give "y"
instead of "m" for the config entries - bear in mind that you may need
other modules for MEGARAID driver to work - lsmod should give you
details of which modules are linked to which other modules. I think for
example SATA requires SCSI drivers to be built too).
