All those programs in userland that aren't running don't have anything
to do with boot up time.

You may benefit from tweaking the buffer cache parameters. The
default for vm.execmin of 5%, for example, works out to only 500Kb
on a machine with 10Mb of RAM, which is too small to have any effect.
Try bumping that to, say, 8% to 20%.  Like so:

    echo vm.execmin=10 >> /etc/sysctl.conf

and see what difference that makes to bootup time.
