Not really.

I do parallel startup on my FC2 boxes. Some info here:

Shrug. Works quite well, greatly reduces boot time.
Doesn't need any hacking of the initscripts except to use chkconfig to
turn everything off, because they're specified in the config file.

It only parallelises the init.d scripts; the preamble is all serial
still. There's some stuff in there I can probably turn off but obviously
not for the general (unknown box) case. But just parallelising the init.d
scripts is a significant win.
