Agreed.. you don't need (or want to) run depmod on each boot.

Hrmm.. not sure if that is truly the case with the ordering, though. 
Mine, for example, on my FE looks like:
alias scsi_hostadapter sata_via
alias snd-card-0 snd-via82xx
options snd-card-0 index=0
options snd-via82xx index=0
remove snd-via82xx { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
odprobe -r --ignore-remove snd-via82xx
alias net-pf-10 off
alias char-major-61 lirc_serial
options lirc_serial irq=4 io=0x3f8
install lirc_serial /bin/setserial /dev/ttyS0 uart none ; /sbin/modprobe
--ignore-install lirc_serial
alias eth0 via-rhine
# nvidia kernel module
alias char-major-195 nvidia-1_0-9755
alias nvidia nvidia-1_0-9755
