This one.

Tell mkinitrd that you have module xxx built into the kernel rather than
a module. 

So for example:
mkinitrd --builtin=megaraid2 -k -o /boot/initrd-2.6.16-xen 2.6.16-xen

Of course, this will NOT work if you haven't configured megaraid2 in the
kernel as a "y"... Check your configuration before you try this.
