so just to state the obvious: this code is not needed to boot fast. It is mostly a workaround for having a bad initrd; if you don't use an initrd, or if you use an initrd that's made with the right device nodes in it already, you really just don't need this.
I would much rather that you just fix your initrd... than to put this sort of thing into the kernel....
