Module autoloading works fine for me, including PPP and getting
all isofs/cdrom/ide-scsi/etc stuff loaded when mounting a CD.

Relevant .config:

CONFIG_MODULES=y
CONFIG_MODULE_UNLOAD=y
CONFIG_OBSOLETE_MODPARM=y
CONFIG_KMOD=y

Sample /etc/modprobe.conf:

# ethernet
alias eth0 tulip

# sound
alias sound-slot-0 emu10k1
alias char-major-14 emu10k1

# ide-scsi
alias scsi_hostadapter ide-scsi

# AGP
install agpgart /sbin/modprobe --ignore-install agpgart && /sbin/modprobe intel-agp
remove agpgart /sbin/modprobe -r intel-agp ; /sbin/modprobe -r --ignore-remove agpgart

# /dev/rtc
install char-major-10-135 /bin/true

# parport
alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=7 dma=3

# ftape3
options ftape ft_fdc_base=0x360 ft_fdc_irq=6 ft_fdc_dma=2

#
# STANDARD STUFF

alias block-major-11 sr_mod
alias char-major-6 lp
install char-major-10 /bin/true

If you're running a RedHat system, you'll also need the following
patch to /etc/rc.d/rc.sysinit. Without it the kernel's modprobe and
hotplug functionalities will be disabled by rc.sysinit.

(RedHat users should also comment out or remove the /sbin/update line in
/etc/inittab, but that's unrelated to the use of modules.)
