No
Boot scripts _must_ be executed in a predefined order.
I was playing a liitle with this and i can give you the 
following advice:

1. Bash is the most executed program in the init scripts
to speed up boot process you must speedup bash.
Some people suggest to make statically linked. This is 
my sugestion too. Loading every shared library takes time.

2. Use a script to start your daemons not 20. 
I use Slackware which has one script for each runlevel. 
Believe me. There _is_ a difference compared to Mandrake 
for example. 

3. The disk load has an impact on speed also.
If you start 5 processes in parralel they will start slower
than 5 scripts sequentially because of the loading of every
script in the same time.

4. A bigger processor cache also helps a lot :-)

just my 2 cents.

Sorry for the off-topic answer in linux-c-programming
