I haven't seen the code yet but I'd assume you could add only the ucode
as an initrd image to the bootloader using "initrd... ". Then you'd only
need to be able to load initrds.
Also, I'd assume we need some of the current functionality to be able to
load ucode without rebooting the box.
But why, do you see a better option for how to tell the kernel to load a
binary blob early at boot?
