I am aware of this. That's why I'm starting preload with sequence
number 95, which should make it start very late at boot time.

It seems to me that you've customised your system somehow. The
behaviour you describe makes it sound that you're switching to
runlevel 2 after S and then to 4 or 5 and have defined most of the
services to start in runlevel 4 and/or 5.
The default is to start all services meant to be run in multi user
mode on run levels 2-5 and stick to 2 after S.
Could you send me the output of "who -r" and files /etc/inittab,
/etc/init.d/rcS and /etc/runlevel.conf?
What's the fun of an uncustomized system? :)
