36 modules are loaded during boot.

I'm using module-init-tools 3.8 and yes I have the following *.bin files
in /lib/modules:

modules.alias.bin
modules.dep.bin
modules.symbols.bin

I've just tried on a tiny sony vaio centrino laptop which loads 71
modules during boot. Its log shows 1.4 seconds between the first and the
last event.

Should I accept those timings and go on or should I be unhappy about
them and try to dig more?

I'll check the bootchart output but fairly I really hate its way of
drawing the booting sequence :)

Thanks a lot
