To be technically accurate, these are init options, not kernel options.
The kernel passes them on to init, which is a regular program, except
that it happens to be the user-land process started.  (I think the kernel
passes on all options it doesn't know about to init, but I'm rusty on
this so don't take it as gospel (which you never should from some random
guy on the Internet anyway)).

Well, it won't complete booting - it had started.  And that's the
whole crux of serial vs. parallel.

If you're still inclined, have a read of
<http://tldp.org/HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html>.
It won't described "modern improvements" like haldaemon, but the
concepts are sound.
