The answer varies based on your deployment mechanism and
requirements. For example: some modules like the kqemu, nvidia,
vboxdrv, etc, etc don't need to be loaded until later on in the boot
process. That being said, if I'm netbooting I don't need to load
storage drivers and the like until later on (unless I want to do some
sort of mountroot manipulation, need to have a working kernel dumpable
device at boot, etc).
