It doesn't have to be in the initrd, but some distro's like gentoo have the option to build firmware\microcode into the intrd. genkernel specifically gives a flag to do just that. Not only that but you also have the option to build them straight into the kernel image. make menuconfig inside /usr/src/linux and you'll find the option in there.
