Bootchart on Gentoo

Recently I tried to chart out my system's boot-up. I got bootchart on my new Gentoo. Then I added a line to my menu.lst as described at the bootchart site and rebooted to test my boot-up. Here is what I got.

I read little more about it and found that I can turn on RC_PARALLEL_STARTUP in /etc/conf.d/rc to get slight improvement in speed. I read that in the comments of the rc file. It was also suggested that I should turn on RC_VERBOSE. So I did it. I got a five seconds increase.

Here is the output of uname -a (I have cut out unnecessary parts like system time)
Linux 2.6.27-gentoo-r8 #1 SMP i686
Intel(R) Core(TM) Duo CPU T2300 @ 1.66GHz

Here is the bootchart with a scheduled filesystem check.
