I still say that you want to be carefull in removing modules from being
loaded. For example the USB modules below arn't being used at the moment.

Now you plug something into the USB, and it won't work, because the necessary
modules arn't loaded.
Again, looking at your soundcard module, as below.
snd_hda_intel 24281 0
At the moment it is using nothing, so it seems.
I've just looked at my /sbin/lsmod, and my snd-ens1371 was showing a 4.
I stopped the Internet radio, and this has now gone to "1". I don't know whats
still using the soundcard, but it's sufficient to say that if you remove the
soundcard module, and do want sounds, you will no longer have them.
btw. I have just restarted Internet radio with Opera, and snd-ens1371 has gone
from "1" to "4" again.
Some modules may be showing a "0", but when you plugin a USB device, or start
some app that uses the soundcard, this scenario may change.
Personally I couldn't care less if my OS boots up in 2mins, 5mins, or 10 mins,
as long as it boots up.
Just my 2¢ worth
Nigel.
