The stickiest part of all of this is where to leave the microcode so
the kernel can get to it way early.  We could use the linked list, but
that would mean bootloader enabling; another idea was to stick it as a
prefix to the initramfs identified by a signature.

I think it would be easiest for the multiboot case if it were a separate
file, but I don't feel I'm really up on all the details.

For the multiboot case, yes of course.

Some bootloaders allow initramfs to be concatenated from multiple files; unfortunately I'm not sure if Grub ever grew that capability. Sigh.
