Oh well, you only need to do an initrd which is not that big of a deal.

The built-in method requires you to rebuild the kernel when there's
new microcode but new microcode is a relatively seldom occurrence
in practice. The last two years putting my statistics completely
out-of-whack.

But they should be coming back to normal because there should simply
be no more room for microcode patches anymore in the most x86 CPUs out
there. :)

So if you're building kernels often, it doesn't really matter if you do
initrd or builtin microcode.
